Profiel Field: radiobutton to single-selection menu
 

Is there anyway to turn radiobutton profile field into single-selection menu?

Not easily, as far as I can see, you would need to delete the old one and then create a new one, as the way the profile field works is that you select the type of field first before you get the other options to change.

But the downside of this is that the new profile field would have a new name fieldx - where the x is the next available field id available.

try ...

UPDATE 'profilefield'
SET
type='select'
WHERE
profilefieldid=XX;

EDIT XX to whatever the profile field ID is; also, you may have to add table prefix if you have one.

Thank you very much!
