Recently I was coding up some asp.net forms and when I started to dig in a bit, I noticed that the creative called for some select combo boxes that used optgroup tag.
For example
<select>
<optgroup label=”Some Band”>
<option value=”song1″>Some Song</option>
<option value=”song2″>Song 2</option>
</optgroup>
<optgroup label=”Some Other Band”>
<option value=”song1″>Song 1</option>
<option value=”song2″>Song 2</option>
</optgroup>
</select>
Well by default the asp.dropdown control can’t handle that case.
Found this nice free suite of tools to handle this case
