So what's clearing the value?

If you are posting back the page to fill in the second list, you should be reselecting the value on the server.

Gayani,

You might want to consider the optgroup tag within the select tag.

 <select size="8">
 
<optgroup label=Test1>
 

<option value="1">one two three</option>
<option value="2">seven eight</option>
 

</optgroup>
 
<optgroup label=Test2>
 
<option value="3">nine tennine tennine tennine tennine tennine tennine ten</option>
<option value="4">nine ten</option>
<option value="5">nine ten</option>
<option value="6">nine ten</option>
<option value="7">nine ten</option>
<option value="8">nine ten</option>
<option value="9">nine ten</option>
<option value="10">nine ten</option>
<option value="11">nine ten</option>
<option value="12">nine ten</option>
 

</optgroup>
 
</select>   

In IE6, it looks like -
