Question

Drop down list width problem in IE

Asked by: andy7789

Hi X-perts

I have a 'select' drop down list which I wanted to expand to a longest element width upon clicking on its elements.

However, in IE, the drop down list does not expand, but is fixed according to the style="width:90px", i.e 90px. It works fine in all browsers except ie.

I tried also:
<select name="select"
style="width:125px;"
onclick="this.style.width='<% = maxOptionWidth %>px';"
onblur="this.style.width='125px';">

it works for all browsers, but ie changes the width of the drop down rather than expanding the element list.

How do I code around this for IE?

Thanks

Andy

Hi,
 Try this sample code for the select box named "sel"
Provisionally, the width of the select box is 10*(length of the text). You may define a different factor as per the font

The Triggering events should be onChange, onFocus and onBlur

<html>
      <script>
            function fnChangeLength(){
                  len = document.forms[0].sel.options[document.forms[0].sel.selectedIndex].text.length;
                  width = len*10
                  document.forms[0].sel.style.width=width+"px";
            }


            function fnResetLength(){
                  document.forms[0].sel.style.width="125px";
            }


      </script>

      <body >
            <form name="frm1">
              <span id="output" name="output" style="width: 360px; color: red;" ></span>
              <br>
              <select name="sel" id="sel" onFocus="fnChangeLength()" onChange="fnChangeLength()" onBlur="fnResetLength()">
                  <option value="0">AAAAA</option>
                  <option value="1">AAAAAAAAAAA</option>
                  <option value="2">AAAAAAAAAAAAAAAA</option>
              </select>
              <input type="text" name="text1" id="text"/>
            </form>
      </body >
</html>

VirusMinus, what is the difference between your code and mine?

All those solutions change the width of the dropdown in ie, but what i am looking for is to get the fixed width (the head of the  list), but expandable below (the list itself) - like all browsers except ie. Is it possible to keep the fixed width of the 1st row (header), but expand the list in ie?

It looks like ie keeps always the same width of the 1st row and the list.

 

by: VirusMinusPosted on 2007-03-13 at 05:37:25ID: 18709501

i added the !important after the width attribute so it overrides any other width settings previously. untested, but just based on a hunch.

Try this solution.

<html>
<head>
<title>Auto Expand Select </title>
</head>

<body>
<br>Following select element will show all the option text on focus, on blur gets back to original width
<br>

<select name="address" style="width:200;" onblur="this.style.width=200;" onfocus="this.style.width='auto';">
<option value="ABC Rockland Road ABC 12  Ave ABC Rockland Road ABC 12  Ave ABC Rockland Road ABC 12  Ave " title="ABC Rockland Road ABC 12  Ave ABC Rockland Road ABC 12  Ave ABC Rockland Road ABC 12  Ave">ABC Rockland Road ABC 12  Ave ABC Rockland Road ABC 12  Ave ABC Rockland Road ABC 12  Ave </option>
<option value="ABC Rockland Road  ">ABC Rockland Road </option>
</select>
<br><input type="text">
</body>
</html>

Guys, thank you for the suggestions, but those really do not address my problem and what i was asking. It is easy to change the width of the list onFocus and onBlure, but i need the width of the drop down header to remain the same in ie - only the drop down list to be expanded.


Pls give me some more ideas, if it is doable at all.
