Hello Gravity owners!
Up to now, by selecting the category button from the Gravity Forms form builder, the only option we had was to go with a drop-down menu. The drawback of this is that we cannot select multiple categories for our forms, leaving out a big part of the functionality we wanted.
Since we wanted to overcome that problem and getting the idea from David Smith (a member of this forum), we extended the functionality and created a plugin that you can not only use the normal post category control where you can select your desired categories with checkboxes but also use a Drop-Down menu, Multi Select or Radio Buttons for your category selection.
As you can imagine, this plugin is distributed for free (GPL) and you can learn more and download in a relevant how to post on our site: Selecting Multiple Categories Addon for Gravity Forms
We have extensively tested it and think that it's a very stable release. If you have ANY problems with it, please do tell us and we'll be happy to help.
Hope it can help many with the same issue and thanks once again to David Smith for giving us something to work on ;)
