To whom it may concern....
Would like to know if it is possible to display the postfield: category as invisible within the front-end of the form so that the user doesn't have to select the custom category in a dropDown although they are posting to that particular category...
So we can setup the postfield: category in gravity forms, insert the category and just hide it from the front-end of the form...
In our case the user posts to a single category and it can look strange to them if they see a dropdown with the category although it is already selected.
