Currently (HTML4.01) and in the near-future HTML5 spec optgroup elements
are used to group options (hence the name :-) and amongst others allow
us to disable a group of option elements at once.
Personally, I think it would make sense to add the ability to make an
optgroup selectable. The result *could* be to select all the childs of
that optgroup element (or simply post the child values as an array or
whatever).
I've searched through the archive and only found discussions regarding
nested optgroups.
In a form submission case it would make sense as optgroups are used to
subcategorize options. If optgroups are used in for example search pages
on websites, it would allow users to only select an optgroup to select
all of it's childs in, as an example, the following scenario:
<select>
<optgroup label="Excel">
<option label="Excel 2000">Excel 2000</option>
<option label="Excel 2002">Excel 2002</option>
<option label="Excel 2003">Excel 2003</option>
<option label="Excel 2007">Excel 2007</option>
</optgroup>
<optgroup label="Word">
<option label="Word 2000">Word 2000</option>
<option label="Word 2002">Word 2002</option>
<option label="Word 2003">Word 2003</option>
<option label="Word 2007">Word 2007</option>
</optgroup>
</select>
Would all of the above make sense? Or don't y'all encounter issues
related to form usability at the moment?
The idea looks good to me, while I am not familiar with possible earlier
discussion of it. Anyway this behaviour should be restricted to select
elements with a "multiple" attribute, where multiple selections are
allowed at all.
