--urgent Can I use table data to create a dynamic drop down menu?

Hi,
I am asked to investigate the possibility of using APEX to create a table driven dynamic drop down menu? The deadline is tomorrow but I have spent quite a bit of time but still have not any clue. Can any one have such experience to point me a way to focus on?
Many thanks.
Jennifer

Thanks you very much for the help Kevin.
Currently my company is using htp.p style to create web app and using the dynamic menu in a similar way as you explained. Now they want to move to Apex and still keep dynamic menu functionality. After reading your response and research I have done I think I can embed it into Apex application by creating the similar table and PL/SQL package and let Apex to call the PL/SQL package when the application is first called. However may I ask you a question about how to call such pl/sql procedure in Apex? .
The current application has the following URL, from which the procedure pkg_main.print_menu is called and html home page with dynamic menu is displayed.
Http://app server:1234/pls/applicationname/pkg_main.print_menu?p_new_window=N
BUT what about the Apex? The Apex URL format is like the following, where 11563 and 1 is application id and page number. Assume that 1 is home page, but HOW the procedure is called, from WHERE?

  • Utilizing Custom Tags to create a dynamic drop-down menu

    Hi to all,
    I am looking to create a dynamic .jsp to display to the user a drop-down list. This list is based upon data in database. The data will be passed as an application bean. This list will vary depending on application criteria.
    I would like to use a custom tag to create the drop-down menu. I am attempting to keep the .jsp page strictly .jsp, no Java. (I have been successful in creating & using an iterator tag.)
    Can someone point me in the right direction, or give me an example?
    thanks!

    What exactly is it you don't know how to do? Write a custom tag or write database access code?

  • Can I change the order of lines in a drop-down menu?

    Can I change the order of items on a drop-down menu? Specifically, the "open" menu that comes up when I right-click on a link.
    Putting "open in new tab" on top of "in new window" makes sense, of course, since it is used more often. But I do a lot of surfing, and had the old position in muscle memory. Re-training my brain to click on the first line instead of the second is taking a long time, and makes me grumbly.
    I'd love to put it back to the old order. Can I? and, if so, how do I do it? (Please give me detailed instructions, IOW, please assume I am a complete simpleton, because sometimes I am.)

    And my old desktop, which has, yech, Vista. (I haven't upgraded it to F4 yet.)

  • How can I organize data by name in a drop down menu?

    I created a spread sheet with several drop down menus. The problem I am having is how to organize my data by name. Every new entry is at the bottom of the drop down and can't be moved to a different location. This gets very confusing as I add more names to the drop down cell. In this case my entries consist of Chemical names that make it very hard to recognize or to locate once I open the drop down menu. Any suggestions?

  • Creating a new drop down menu when an option in an existing one is chosen

    I’m using Coldfusion 9,0,0,251028 on Windows 7 64-bit, with a Microsoft Access 97 database. 
    I’m having a problem with using a drop-down menu to create another one below it once a certain option is selected
    (in this case, the option named “Breaking News”, which has an id of 31).
    What event trigger should I use to create a drop-down menu underneath the first one when “Breaking News” is selected? 
    Should I be using Javascript for something like this, or can Coldfusion handle it?
    Here’s the code:
    <cfquery name="get_info" datasource="#db#">
    select * from lists
    order by department asc, list asc
    </cfquery>
    <div align="left">
              <select name="list">
                     <option value="-1" selected> --------------------------------------  
                     <cfoutput query="get_info" group="department">
                            <cfoutput group="list">
                 <cfif list neq "Breaking News Cell Phone">
                         <option value="#id#">#list#
                 </cfif>
                            </cfoutput>
                  <option value="-1"> --------------------------------------
                     </cfoutput>
              </select>
    </div>

    Depending on the details, I might use ColdFusion to create the content of the second drop down.
    The second drop-down is supposed to be an expiration date that gets attached to the message so it can be self-removing.
    The first drop-down is to specify a category for a message to be sent out on.
    In this case, the only one that needs the secondary expiration drop-down is a single category (Breaking News),
    so all other options on the drop-down would have to not trigger the expiration date drop-down showing.
    In that situation, would you use ColdFusion to create the second drop down?

  • 'Weird' Terminology: rigs, snapshots and checkboxes/My odyssey, to create a simple drop-down menu ;)

    The Preface
    I'm a hobbyist! "Daddy does movies", enthusiastic about the -zillions of features, tools like FCPX and Motion5 offer! I'm no designer, no engineer, no 'pro'. My goals are sky-high, results more down-to-earth
    This is no request for help, just to share my … quest for a 'simple' effect. Or feature… Or box.-
    In hope, it helps YOU to solve your problems…
    The Issue
    Simple: I wanted to create my very own 'title' template for FCPX. Concept: a lil' animation, the two teams logos reveal a lower third, showing the actual score. Plus, an insert showing the scorer (=my kids love to see themselve in such 'sports graphics' )
    Usually, I 'manufacture' such graphics as single Motion-Projects. This time, my goal was a template, my kids slaughtered in the first season's game the other team by 11:1 (which is in soccer…  a goal-fest) To 'built' each Title manually as individual Projects would spend too much time. I needed a template! … so, step #1: using a Dropzone for opponents logo - easy. Animating - been there, done that, easy.-
    But that 'show players face&name' … 18 team-members… wouldn't it be nice to have some 'drop down menu'?
    How to accomplish that?
    The Manual, with all respect, is written for experts. Describing ALL options in one sentence. I need a cookbook, step-by-step-instruction … My preferred source of imagination, MacBreakStudio/rippletraining/Mark Spencer, hasn't done a tutorial for 'drop downs' yet.-
    My guts told me, it has something to do with 'rigs' …
    The Rig
    I dragged my folder with player-pics into my Motion5 project; there, I could check/uncheck each player. But I wanted these 'boxes' avail in FCPX, I wanted to 'publish' this check-list. Trying 'tis&'tat, I noticed, I can apply to the opacity of each player-pic a Rig. And a Checkbox-rig - hey, that close!!
    … soooo?
    No 'checkbox' in FCPX after publishing my title. No list after publishing to FCPX! What have I done wrong?
    The Snapshots
    I was confused by the meaning of  'snapshot'! … and since it made "ping!" in my head, it's so simple:
    As I would done it in a 'manufactured', single Motion project, I have to select each team-member, create a New Snapshot, set opacity to show only this player; create another New Snapshot, showing a diff. player. … and so on, and so on.
    … for sure, for convenience I renamed each Snapshot to each Player's name…
    In my amateurish mind, I had the imagination, Motion5 would offer me a 'behavior' (or 'filter' or whatever) to create checkboxes; or drop-downs; … uhm, well it does, but for me the work-flow is back-to-front: first creating a status-quo, then tell 'this is option#1/#2/#3' … I had the idea, you can select first an 'empty box', then drag its content into it. I've learned: professional don't tic this way.
    Eighteen Snapshots later …
    The Result
    After publishing my hand-crafted Title, it appears like that in FCPX:
    The Dropzone is to apply the actual contestants team-logo; the 'Title' is the score, just type the number; and - finally! - I had my drop-down-menu, listing all players,  for simple selection.- Me happy … !
    In movin' images:
    http://youtu.be/wIeu1cVMu94
    As mentioned before: the design isn't meant to win a price; and most probably, there are 'shorter ways to Rome' … so, if any of you 'pros' like to comment or recomment a 'better', in terms of 'easier' way, don't hesitate to teach me!
    K.

    Motion-guru Marc Spencer from rippletraining.com has an episode upon Rigging at MacBreak Studio
    MacBreak Studio - Episode 151: Setting up a Rig in Motion 5 for Final Cut Pro X    
    … I'm no expert (as you notice in my first post ), but I'm really overwhelmed by the endless options, esp. in correlation with FCPX… on first sight, 'rigging' looked like 'bundled color sliders' to me, but by creating your very own drop-down menus you can create extremely powerful tools, handcrafted for your very own needs.
    For sport-reports, with its tons of statistics and inserts, you can create a box of 'title genrators' - once done, multiple times used, and extreeeemly fast then.
    … And when a 'nnob' like me manages it, it is really no rocket-science…

  • Oracle apex creating mouse over drop down menu

    Hi ,
    I want to create a drop down menu for main tabs. Can any one explain or tell how to create this drop down and to use that in oracle apex 4.2 version.

    A much better option than using in-built tabs.
    1)
    You need to define a List, either static or dynamic, which will be your menu options - and it needs to be hierchical.
    Then you create a list region on the global page, using a stock template such as DHTML Tree
    2)
    Or you can use a CSS only menu, similar to the first option
    http://www.grassroots-oracle.com/2013/05/css-pull-down-menu-using-apex-list.html
    3)
    Or you can use a plug-in

  • Populate a table field from selection made from drop down menu

    Hello all,
    I'm having a bit of head scratching problem that i just can't get my head around. I'm using Dreamweaver CS4
    and phpmyadmin for my site.
    I have a form that inputs a record into a table in my database.
    The form is a user picking a fantasy sports team. A user selects a player from a drop down menu.
    The players name is got from a recordset that accesses the player database, with the values coming
    from the id field and the values from the name, so a user selects a player by there name and not
    there unique id value. The code for this is as follows:
    <tr valign="baseline">
    <td nowrap="nowrap" align="right">GoalKeeper:</td>
    <td><select name="gkid_team">
    <?php
    do {
    ?>
    <option value="<?php echo $row_rs_pt_gk['gkid_gk']?>" ><?php echo $row_rs_pt_gk['gkname_gk']?></option>
    <?php
    } while ($row_rs_pt_gk = mysql_fetch_assoc($rs_pt_gk));
    ?>
    </select></td>
    What i'm trying to achieve is that when a user selects a player from the drop down menu, their price is displayed in the table cell next to the menu. The value is held in the same table of database as the names and id values. I need to do it so the page doesn't need to be refreshed so i assume i need to use some sort of javascript, php and/or maybe ajax. However with java and ajax i have very little or no experience so i'm not really sure what i'm doing. I've been on numerous forums, looked in text books and have been searching the net for hours but i can't seem to solve this problem.
    Any help or advice would really be appreciated as i just can't seem to get my head around it,
    Thanks,
    pb1uk

    can this be done??? thanks in advance annieYes.
    One way of doing it is submitting the form on change of the selected value and fetch back the query results. Have a servlet invoke the method and set the results in the request.
    Another way (not recommended) is to fetch the results corresponding to all the values in the dropdown and have it in the session. The latter solution would obviously be slow.

  • I can't find the answer....about drop-down menu's

    This is my first post, but after looking everywhere for the
    answer I decided this is my best option. I am trying to create a
    drop-down menu with an option for SELECT ALL which would select all
    from a table's field via a select statement via a URL parameter. I
    have tried inserted the value's *, %, and -1 but none of them have
    worked. Do you know what I would need to do in order to select all
    the values in a table (this one lists zip codes)?
    Thank you again. If you have an answer to this you are my

  • Can't Block Person in iChat, with task bar drop down menu in Buddies.

    Hello : )
    I was wondering if anyone knows how i can use my "Block Person", on iChat (task bar with drop down menu in Buddies). I am pretty sure this worked has worked before , the command is there it just seems to stay greyed out. I know it can be done in the Security tab / ichat preferences, I would like it to work under the Buddies drop down as well. I know it did before, my HD was replaced. Help would be most appreciated.
    Thank you for your time.
    Eme;~[)

    Hi Eme,
    Ok. iChat 3 has a setting that needs to be set if you are going to use the same screen name on two copmuters or on two apps on the same computer.
    Go to iChat > Preferences > Accounts
    Select the AIM account in question in the left hand column
    Select the Account Info tab.
    Log out of AIM (iChat menu)
    Check the check box "Allow Multiple Logins for This Account"
    Log back into AIM.
    If this is not checked starting iChat 3 will boot off (log out) any other AIM Client using the same screen name whether it is on the same computer or not
    From what the ISP says and what you have posted here it seems the modem is in Bridge mode.
    I take it if you open System Preferences > Network > Select Airport from the second drop down > TCP/IP tab you IP is shown as 10.0.1.2 ?
    And the drop down just above that says "USING DHCP" ?
    This would mean the Airport is in default mode and Issuing Addresses.
    Also by default an Airport would do NAT. (Network Address Translation)
    This measn the Airport sorts out where each bit of data has to go.
    It is different from other routers as you don't have the specify which ports are going to whch ports on one IP (Port Forwarding)
    Which Netopia device is it ?
    3347 ?
    If it is this one you may need to look at the QoS settings.
    These are setings that are supposed to protct you form reciveing data too quickly. (helpful if you are running a busy web site but restrictive sometimes for iChat).
    As you are omly talking about sorting out Block lists it is prpobably the multiple login option that needs doing.

    I just installed PS6 and while cleaning up a picture I found this very frustrating: I created a new layer on top of the one I'm editing and wanted to remove a couple of blemishes. but when I hit J and try to select the 'all layers' option from the drop down menu, it won't allow me… it's stuck on 'current layer' and I can't seem to change that… Does anyone else have the same problem?

  • Can't select number and type of tracks from drop down menu!

    When I create an empty project you are supposed to be able to select the number and type of tracks you want from a drop down menu. This menu worked when I opened logic for the first time. In subsequent new projects this window does not drop down fully and I'm unable to make any selections!
    Can anyone help?

    Thanks for your replies.
    I tried Eriksimon's solution which worked the first time i re-opened Logic, but reverted back to how it was everytime after that!
    As you'll know when you launch Logic you get prompted to choose a template, so i slect empty project, then when the main window opens you're prompted with New Tracks drop down/pop out box. What I should get is a choice of Type - Audio, Software Instrument and External MIDI with another section underneath with Format, Input, Output etc... All i get is Number of tracks to choose and External MIDI as the only option! Even if i create the track any subsequent tracks are all External MIDI, no other options!
    When i installed Logic i left off the Jam packs as i'm short on HD space at the minute, i don't think this would be the cause but it's the only thing i've left out of the installation. If i have to re-install i will, but it took nearly 2 hours!
