Using scroll bar in Select object but preventing selection of option.

I have a situation where, some users are only allowed to view the list options in a select control, but they are not allowed to alter the selection(s). If I use the disabled property, the scroll bars are disabled and they cannot see all the options. How can I get round this?

As you've probably gathered, the readonly attribute is not available for a Select Box control. Normally the user would not be able to modify the values anyway, so I'm not sure what you're attempting. Can you be more specific?

The user needs to be able to see all the possible options that could have been selected by an authorised user even though they cannot alter the selected option(s). The options will vary depending on other values in the screen.

Hmmm... is it possible for you to simply present the options as a text-based list instead of a select box, whenever the disabled condition is true?

Or failing that, list the options in a textarea - which can be readonly, instead of the select box?

That works fine if there is only a single selection. What if there are multiple selections allowed?

Just as an afterthought, you could have the selected items appear with a different style. It doesn't prevent selections, but makes it appear to the user that they're fixed.

<html>
<head>
<title>none</title>
<style type="text/css">
<!--
.selected { background-color:FF0000; color:#FFFFFF; }
//-->
</style>
</head>
<body>
<p>Selected options are displayed in red.</p>
<select multiple name="MySelect" size="5" >
<option value="A" class="selected">This is option A</option>
<option value="B"> This is option B</option>
<option value="C" class="selected">This is option C</option>
<option value="D"> This is option D</option>
<option value="E"> This is option E</option>
<option value="F" class="selected">This is option F</option>
<option value="G"> This is option G</option>
<option value="H"> This is option H</option>
<option value="I" class="selected">This is option I</option>
</select>
</body>
</html>

So what's the answer for multiple selections?

I have done the following:

<html><head><title>none</title>

<script>
// Functions to backup and restore Read-only list boxes
function backupReadonlyOpts(obj) {

      var ary = new Array(obj.options.length);

      for (var z=0; z<obj.options.length; z++)
      {
            ary[z] = obj.options(z).selected;
      }
      obj.save = ary;
}

function restoreReadonlyOpts(obj) {
      for (var z=0; z<obj.options.length; z++)
      {
            obj.options(z).selected=obj.save[z];
      }
      bCtrlReadOnly = true;
 }
</script>

</head>
<body>
<select class="selcls1" multiple=true size=3 style='DISPLAY: auto' save="" onFocus="backupReadonlyOpts(this);"
   onChange="restoreReadonlyOpts(this);">
<option value="A"> This is option A</option>
<option value="B"> This is option B</option>
<option value="C" selected> This is option C</option>
<option value="D"> This is option D</option>
<option value="E"> This is option E</option>
<option value="F" selected> This is option F</option>
</select>
</body>
