Why is that a problem?
Say your code has
<SELECT>
<OPTGROUP label="books">
<OPTGROUP label="fiction">
<OPTION>Treasure Island</OPTION>
</OPTGROUP>
<OPTGROUP label="nonfiction">
<OPTION>Art of War</OPTION>
</OPTGROUP>
</OPTGROUP>
....
</SELECT>
The compliant browser would render
[BOOKS >]
[fiction >]
[Treasure Island]
[nonfiction >]
[Art of War]
...
while an older browser would show
/BOOKS/
/fiction/
Treasure Island
/nonfiction/
Art of War
...
I don't see a problem with that - it looks like perfectly graceful
degradation to me...
