[dev] Horde_Form radio with text ("Other" option)

[Richard Wallace]

Hey guys,

What would be the best way to create a radio button variable with an 
"Other" option that requires the user to fill in the text box.  Right 
now I'm thinking of making the separate text variable required based on 
whether or not the radio button is selected.  So the first time the form 
is viewed, the text box wouldn't be required, but if the user selects 
the "Other" radio button and hits submit, the text variable will be set 
to required so the validation should fail.  Does that sound like a good 
way of doing it?

Thanks,
Rich
