[TYPO3-project-formidable] Multiple values from LISTBOX

[Luc Muller]

Well nevermind ;)

I'm going to add it in the future, because it's a not so used feature 
provided by html.
but could be very useful for some specific task.

well you could have a look at this html structure, you'll understand how it 
works :)

<select>
<optgroup label="Swedish Cars">
<option value ="volvo">Volvo</option>
<option value ="saab">Saab</option>
</optgroup>
<optgroup label="German Cars">
<option value ="mercedes">Mercedes</option>
<option value ="audi">Audi</option>
</optgroup>
</select>

for exemple it can be useful to select a job.
lots of time you got to use two listboxes to select you job.

with the firstone you select de domain of you job (computer science, public, 
financial)
and then with the second after a refresh, you can select your job 
(developper for computer sciences, social worker for public etc.)

with the optgroup, everything can be included inside only one listbox!

Hope this helps ;)
