How to set width of a select list?

Hi,
another newbie question from me :-)
When I create a select list the default width is 30, no matter what I set this value to the width of the select list stays the same, it gets as wide as the widest element in the list. This messes the design of the page. I f I have three select lists in a column I want them to have the same width. How do I accomplish that?
/Magnus

Edit the item and in the HTML Form Elements Attributes field type the following:
style="width:120px";adjust the 120 to whatever width you like

  • How to set width of apex_item.select_list_from_lov?

    Hello experts!
    Sorry to bother you but I can't find out how to set the width of a select list generated in my query.
    I already had a look at the Oracle Express Api docu but and tried the following to no avail.
    apex_item.select_list_from_lov(8, a.lng_arbeitsschritt, 'Auftakt_LOV','.style.width = "300px";',
    '%', null,null, null, 'class="combobox"')Do you have a better idea?
    Many thanks,
    Sebastian

    I just did some more testing and discovered that the following works:
    apex_item.select_list_from_lov(8, a.lng_arbeitsschritt, 'Auftakt_LOV','style="width:500px";',
    '%', null,null, null, 'class="combobox"')Maybe this helps others as well!
    Thanks for having a look!

  • How to Build an Auto-Expanding Select list

    Hi everyone,
    I want to know if it's possible How to Build an Auto-Expanding Select list ?
    I saw some discussions which tell us to use Jquery to acheive this. Is it the only solution ?
    I want a solution that it is easy to implement.
    Thanks in advance. Bye.

    Hi,
    Not sure what you've seen before, but anywhoo:
    In my select list, i set element attributes of :
    style="min-width: 130px"Just because some of the smaller values were getting truncated.
    Then I add this onload javascript code:
    $('#P10_AUTO_EXPANDING').change(function(){
      $(this).width($('option:selected', this).text().length*10)
    })It's not perfect for getting the right size (i.e. i think it increases exponentially, but you can play around with the multiplier)
    Which you can see: http://apex.oracle.com/pls/apex/f?p=45448:10:
    Edited by: trent on Dec 15, 2011 10:35 AM
    Probably best to add this line of code:
    $(this).width($('option:selected', this).text().length*10)
    into a dynamic action for a change event of the item, of which the true action is to execute javascript code.

    How can i do that???
    Regards,
    Sakthi.

    Hi Sakthi,
    Yo can use the Java script for that..
    Dynamically the value will come into text box.
    Use the below script.
    <script type="text/javascript">
    function disFormItems()
    var lReturn = $v(here your select list name)
    alert(lReturn);
    document.getElementById(here your text box name).value =lReturn; }

    Hi
    You can create a search for that field with more than one fields and yu can add the search help for that field
    see the doc
    1) Elementary search helps describe a search path. The elementary search help must define where the data of the hit list should be read from (selection method), how the exchange of values between the screen template and selection method is implemented (interface of the search help) and how the online input help should be defined (online behavior of the search help).
    2) Collective search helps combine several elementary search helps. A collective search help thus can offer several alternative search paths.
    3)An elementary search help defines the standard flow of an input help.
    4) A collective search help combines several elementary search helps. The user can thus choose one of several alternative search paths with a collective search help.
    5)A collective search help comprises several elementary search helps. It combines all the search paths that are meaningful for a field.
    6)Both elementary search helps and other search helps can be included in a collective search help. If other collective search helps are contained in a collective search help, they are expanded to the level of the elementary search helps when the input help is called.
    CREATION:
    Go to SE11  Tcode
    select search help
    give the 'z' search help name and create
    select the selection method ur table name eg : 'mara'
    dialog module 'display value immediately'.
    add the field whatever u want and lpos = 1 and spos = 1 and check import and export parameter.
    where left position when displaying and spos = search position
    and then save and activate ..

  • How can I get two column selection list in my html form

    I required to have two column selection list in my jsp page to show name and description of a product. How can i achieve this functionality or is there any other alternative to do so.

    If i understand correctly: you can't actually create two columns in a list because it can only hold one value. The only way to achieve what you want is by concatenating the two values you want to display and put this as the value of the listbox.

  • How to set width of a vertical scrollbar (such as in a combobox)

    I have a combox. I have successfully figured out how to set the font name and font size for each time, however as I have increased the normal very tiny size of the combobox items (now more legible), the remaining last problem is the measly 16 pixels for the scrollbar. This might be acceptable on a desktop with a precise cursor positioning system, but for mobile apps I need a way larger scrollbar thickness, perhaps 30 pixels. How does one set the scrollbar thickness for a combobox? I am willing to stick with scaled up icons from whatever is being drawn as a default, so if possible I would just like to set some style number. But can't find any documentation on this. The Apple system has a nasty fixed width scrollbar (20 pixels), and so far it seems Adobe Flash is using only 16. Great for when you are cramped but I am trying to UN-CRAMP the user interface!
    any help is greatly appreciated.  A free copy of Discus ($40 value) for whomever helps me solve this vexing problem with the least amount of effort!

  • How to set Width of a JPanel?

    I am overwirting paintComponent(Graphics g) method to
    draw some g2D in a JPanel.
    I want the drawing processing shown on screen (not flashed out after drawn because it is VERY SLOW).
    So that I CAN NOT use setsize() or setBound() because to change JPanle.width because this is NOT what I wanted(the graphics is shown AFTER is drawn).
    Everytime I call paintComponent(), the width of JPanel is changed.
    My question is : How can change JPanel.width without calling method like setsize() or setBound() .
    Thanks a lot!!

    My code too large, I just show some idea here:
    class caller (){
    myPanel p;
    Graphics2D g2 = (Graphics2D)p.getGraphics();
    //I nee to increase the p.width before call my_paint
    //I CAN NOT use setsize() or setBound()
    //because I want show the drawing process
    //on screen( and that is fast)
    p.my_paint(g2); // how to set p.width ??
    public class myPanel extends JPanel
    public void my_paint(Graphics2D g2)
    //Do my drawing here ,
    // I need to draw thousands of Line2D.
    public void paintComponent(Graphics g){
    Graphics2D g2 = (Graphics2D)g;
