Hello,
There is a couple different ways to do this here is a link to one way

and here is a link to another way

If neither of these work for you just do a search for select list in the forum and you'll get quite a few hits.

Loading multiple dependent select lists

What is the best way to load select lists that are dependent on the previous one?
ex.
Select School
based on school you select the subjects
select subject
based on subject you select the courses,
etc
I'm trying to stay away from as much javascript as possible.
thanks for the help!

You can use javascript, or resubmit the page and laod the dependant select list based on what was selected.

Embarrassing questions.. :/ Dependent Select Lists

One more embarrassing question to feature my narrow knowledge.
I want to create dependent select lists. Have tried following the procedure as in help:
<p>You can have one LOV drive another LOV by: </p>
<ul>
<li type="disc">
<p>Creating a basic form. </p>
</li>
<li type="disc">
<p>Defining two lists of values. Note that the driving LOV must submit the page after a value is chosen. </p>
</li>
<li type="disc">
<p>Defining a branch that branches back to the current page. </p>
</li>
</ul>
<p>Consider the following example. The first LOV enables the user to pick a state. </p>
<pre xml:space="preserve">SELECT state_name d, state_id v FROM states </pre>
<p>The second LOV selects the country name and country ID based on the state selected in the first LOV. </p>
<pre xml:space="preserve">SELECT county_name d, county_id v FROM counties WHERE state_id = :Px_STATE_ID </pre>
I try to follow the procedure and I get nothing in list two.
I am trying to make it this way that if a country selected in 1st list then only regions to that country get listed in 2nd select list.
Can someone "spell" this out for me? With an example? I had previously asked similar question here and never figured out solution out of it, so I am embarrasingly asking once more...
Hrefna the persistent

Hi Earl,
Can you please help me out? Hope so.
I then created a page with a text field called
P1_EMPNO.You're not using select list items on the page? That's what this thread is about - although the specifics can be adapted to other page item types.
I added onblur="get_AJAX_SELECT_XML(this,'P1_ENAME')"
in the Form Element Attributes.
My question is, how do I create P1_ENAME? Is it a
LOV, text, etc.Don't know. What are you trying to accomplish? I thought you wanted one select list item to help you narrow down the number of items in a second select list - but it sounds like you've got something else going on. Please explain exactly what your UI requirements are.

How to create dependent Select Lists?

Hi,
Found in the documentation that to create dependent select list we have to do these 3 things:
1. In the parent select list, choose the option "select list with submit".
2. Defining a branch that branches back to the current page.
3. In the child select list sql, use the value of the parent (eg. :P6_PARENT_SELECT_VALUE).
When I change the value of parent select list the page is getting submitted and its going to the parent page. I've a branch that goes to the parent page but how to create a branch that comes back to the same page and then use it in parent select list?
Thanks,
Hozy

Hi Hozy,
1. Make the branch conditional...
2. Create a new branch while will run when you make a selection in parent select list.
Also check this site to create dependent select list without sumbitting the page....

AJAX dependent Select lists

Can anyone please help me figure out where am going wrong?
I have 2 regions on page 1. Region 1 is supposed to have 2 drop down lists (cascading i.e values in second drop down Drop List HJ are dependent on value selected in first lov Ajax Select HJ). Region 2 will be a report.
I am trying to create AJAX cascading lovs based on eg. provided on carl's application so that Region 2 is not refreshed each time I select a value from the drop down's
[http://apex.oracle.com/pls/apex/f?p=36391:37:1510004986327720::NO:RP::]
I have downloaded the application and tried to do the exact same steps, but my child lov is not updating its values after I select a value from in Ajax Select HJ.
My application is available at http://apex.oracle.com/pls/apex/f?p=33829:1:2010637670427735:::::
Appreciate any help on this
Thank you
Deepu

Thank you Denes !! The example really helped me. Now I am stuck at the next level. I am new to apex and learning and building dashboard for my organization. So, please bear with me.
I have a page that is divided into 4 regions. Each region displays a chart that is generated dynamically. When I say dynamic, each region has 2 drop down lists.
First pull down has Org and Year as values, if they wish to view chart by Org or Year. If they choose Org, second drop down defaults to Org. If they choose Year, second drop down displays Year's as 2010, 2009,2008 so on. Depending on which year they choose they should be able to view that Year's chart by month in that region.
Initially I had used select lists with submit for drop down's but that was refreshing the whole page. But now after using your example with AJAX I was able to accomplish the cascading Lov's stuff. Now, after user selects a value in second drop down, is there a way that I can display the chart and refresh only that region each time user selects a value from the drop down.
I want to avoid refreshing the page each time, I need each region to refresh based on user selection in drop down's. Is this possible in apex? Is there any example that you could direct me to.
Thank you so much for all your inputs. Appreciate it very much

You'd probably have to put a copy of the app on apex.oracle.com for a complete diagnosis, but you could maybe just check that the Source Used attribute for teh select list is set to 'Only when current value in session state is null' and not the 'Always' option.

How to do dependent select list based on parent select list

Hello... I have the following bit of code...
*parent select
htmldb_item.select_list_from_query(1,null,'select program_desc_eng, program_id from myfps_programs')
* child select using parent value
htmldb_item.select_list_from_query(2,null,'select sub_pgm_desc_eng, sub_program_id from myfps_sub_programs where program_id = <VALUE FROM ABOVE?>')
I know this is easily done using the select list form items and such but I need to use the htmldb_item function. On screen when a user selects value from the parent select list, I want the child select list to use the value of the parent as a parameter into its own select list. How can I reference the parent? (ie can I use htmldb_application.g_f01(1) or something of this nature?) I realize I may need a bit of javascript to have it work correctly but I'm just wondering if its possible?

This is not a trivial task.

Select List problem

I have 3 select lists: the first two are with submit and the last one is just select list. Each list depends on the previous one.
I have set null and default values for each list. The problem occurs when I first start the application, but after selecting an option in the first list all is fine and when I reset the fields everything works as it should.
So the problem only occurs when the application is first launched....
This is the error message:
Error: ORA-01858: a non-numeric character was found where a numeric was expected performing List of Values query: "SELECT TESTTIME d, TESTTIME r FROM TESTSETUP WHERE TESTDATE = :P3_TESTDATE and TERM = :P3_TERM ".
How can this be corrected?
Any help would be greatly appreciated.
Thank - Greg

I have set null and default values for each list
These values are not available in committed session state for the subsequent select lists to use.
Solution: Create a OnLoad Before Header computation (conditional upon the value of the select list being null) to set it to whatever null/default value you want. This will "initialize" the value so that your dependent select lists can work properly.

AJAX Select Lists on Updateable Reports

All,
I have followed the examples from Karl and Sergio's blog on how to use AJAX to contol dependent LOV lists in a form. My question is, can this be done in an updateable report? I'm having difficulty in determining how to reference the column names of the dependant lists.
What I basically have is a time app. User selects his project from a picklist and then his associated tasks for that project will appear in the task list. I have used the updatable report option to build this rather then a form, because I liked the prebuilt add row and processing functionality.
Anyway if anyone knows how to use AJAX dependant select lists in an updateable report it would be greatly appreciated.
Thanks

Select List with Submit refreshes page to top force users to scroll down

Hello All,
I have Dependent Select List where this functionality driving select list submit values to a subsequent select list.
The "Select List with Submit" refreshes page where the unintended by-product is page refresh, which returns to top of page and therefore force users to scroll back down.
In other words: I have a long form page where I have a Dependent Select List. So when you change the value of the 1st select list it refreshes the 2nd. This is all fine, but when the refresh occurs, the Form-focus returns to the top of page. This makes the users scroll back down to the lower end of the Form where they left off. This would make usability problems for users.
Anyway we can make the Form return where to the area(Item or Region) where the user was during the selection of the Select List?
Thanks in advance,
Konstantine

HURRAY!! I got it to work perfectly using anchors. I am adding this message to help future ApEx developers.
I have been searching the Forum for 3 days and have read numerous postings. There was a lot of good discussion on anchors and linking from page to page. But, nothing exactly like my situation.
Situation: Have a page, PG4, with a button, PG4_BUTTON, that redirects to a different page, PG7. PG4_BUTTON has its 'Display In Region' field set to PG4_REGION. When PG4 is run and the form displays, the PG4_BUTTON is located at the bottom. When the user would click PG4_BUTTON, the user would be taken to PG7. (this is good) The user enters some data in PG7 fields and then clicks a create button, PG7_BUTTON. PG7_BUTTON would submit data. An After Processing, Go To Page, Branch would be activated when this button was pressed and then the user would be returned to a refreshed PG4, at the top. This forces the user each time to have to scroll down to the bottom of PG4 to continue. (this is NOT good)
Solution: On PG4, I edited the region, PG4_REGION. For the region 'Title' I added an anchor before the actual name. So it looked like this:
{a name="REGION_TO_RETURN_TO"></a}PG4_REGION
please note: where I have the curly braces above '{' '}' you need to put < the pointed and '>'
Next, on PG7, I edited the Branch. On the 'Edit Branch' page, in the 'Action' region, I changed the 'Target type' field from 'Page in this Application' to 'URL'.
To the 'URL Target' text area field I added this:
f?p=&APP_ID.:4:&SESSION.::::::#REGION_TO_RETURN_TO
So, there you have it. If you still need to read other postings, here are a couple of the sites I read:

Automatically update text field depending on the in select list value

I have got 2 tables. Table A (Employee Personal Detail), Table B (Employee Academic detail). Employee no is common field between two tables).
I have created interactive report with form on table b using in-built templates. I have added text box on form to display employee name which is stored in table A. I want to automatically display employee name depending upon value in employee no field on form. I know I can write query to get value in employee name field. It gives me error when employee no is blank. How to handle error?

Sagar,
For the employee name value to change according to the emp_no, your page needs to get submitted. can you use a select list with submit for emp_no? And then use the PL/SQL mentioned above to run on page submit?
I'm not sure but I guess you can also achieve this in Ajax. May be someone expert in that could help.

Dynamic select list dependency

Hello,
I want to have two select lists populated dynamically by a query, where contents of one list depend on the choice made in the other list.
For example I have tables CATEGORY (ID, NAME) and SUBCATEGORY (ID, NAME, CAT_ID). I created one List of Values that Category select list is based on: "select name d, id r from category order by 1". This alone works fine.
Now for Subcategory select list I created another List of Values: "select name d, id r from subcategory where cat_id = :CAT_ID order by 1". The where clause is just my guess and it doesn't work (select list is empty). How do I pass the value selected in my first select list as a parameter for the second one?

Select list dependent on textbox

Hi,
I've a requirement to put together a cascading select list. The only exception is that the first select list is a textbox instead of a select list. How to create a select list that is dependent on the textbox? Is there a way to do this in APEX without resorting to AJAX? Is there an example out there?
Thanks

Hi
Try this courtesy of Carl Backstrom...
Create an hidden item called TEMPORARY_ITEM.
Try this for the js:
function get_AJAX_SELECT_XML(pThis,pSelect){
     var l_Return = null;
     var l_Select = $x(pSelect);
     var get = new htmldb_Get(null,$x('pFlowId').value,'APPLICATION_PROCESS=ap_str_typ_lov',0);
get.add('TEMPORARY_ITEM',pThis.value);
     gReturn = get.get('XML');
     if(gReturn && l_Select){
         var l_Count = gReturn.getElementsByTagName("option").length;
         l_Select.length = 0;
         for(var i=0;i<l_Count;i++){
             var l_Opt_Xml = gReturn.getElementsByTagName("option");
appendToSelect(l_Select, l_Opt_Xml.getAttribute('value'), l_Opt_Xml.firstChild.nodeValue)
get = null;
function appendToSelect(pSelect, pValue, pContent) {
var l_Opt = document.createElement("option");
l_Opt.value = pValue;
if(document.all){/* why is ie different ask bill */
pSelect.options.add(l_Opt);
l_Opt.innerText = pContent;
}else{
l_Opt.appendChild(document.createTextNode(pContent));
pSelect.appendChild(l_Opt);
And then amend your On Demand process to this:DECLARE
l_counter NUMBER;
l_o_name VARCHAR2(2000);
BEGIN
OWA_UTIL.mime_header('text/xml', FALSE);
HTP.p('Cache-Control: no-cache');
HTP.p('Pragma: no-cache');
OWA_UTIL.http_header_close;
HTP.prn('<select>');
FOR rec IN (select str_typ_desc from vw_dime where street_name like upper(:P7_STREET_NAME) || '%'
ORDER BY 1)
LOOP
HTP.prn('<option value="' || rec.str_typ_desc || '">' || rec.str_typ_desc || '</option>');
END LOOP;
HTP.prn('</select>');
END;
Then change your javascript call to this...onKeyUp="get_AJAX_SELECT_XML(this, 'P7_STREET_NAME')"
Let me know How you get on.
Cheers
Ben

Select list that is dependent on another select list with ajax

I have a select list that contains it (ajax)
onchange = "get_select_list_ajax (this, 'P2012_REQUERENTE', 'COMBO_REQUERENTE_ITEM', 'COMBO_REQUERENTE_AJAX');" class = "largura200"
So I have a select list below, which is conditional, according to the value returned from the select list P2012_Cliente.
DECLARE
v_tipo VARCHAR2 (50);
BEGIN
SELECT DISTINCT (id_cliente_tipo) INTO v_tipo FROM vw_cliente
WHERE customer_id =: P2012_CLIENTE;
IF (v_tipo = pkg_cfg.c_tp_cliente_interno) THEN
RETURN true;
ELSE
RETURN false;
END IF;
EXCEPTION WHEN OTHERS THEN
NULL;
END;
But is not working .. Why? He is not detecting the return of the select list that is Ajax?

How can I send the return of a select list (ajax) on a text item?
html_form_attributes of sel. list -> onchange = "get_select_list_ajax (this, 'P2012_REQUERENTE', 'COMBO_REQUERENTE_ITEM', 'COMBO_REQUERENTE_AJAX');" class = "largura200"

How to display a value from Select List by default

I have a Select List on a form and I need to on page load show an entry from the SL depending on the user Id of the user logged on. For example, if the SL had 3 entries: 'Div1', 'Div2', and 'Div3', depending on the division the user belongs to (I can determine that from his user Id using a SQL), say, I need to display 'Div2' to the user in the SL instead of the usual NULL or '---- Select Div ----'. 'Div1' and 'Div 3' entries will still be part of the SL, but for user's convenience I need to display their division.
Any ideas?
Thanks,

Hi Ajay,
you need to specify your apex version, database version and so on to make our help specific.
Anyhow you can create a page process- for example one at On Load before header.
For example;
[code]
declare
v_division varchar2(32);
begin
--select default division
select my_division
into v_division
from my_division
where my_division=:APP_USER;
:P_DIVISION:=v_division;
end;
[/code]
Then in the default of your select list, specify P_DIVISION as the default. Using one of several methods
