Firts, I couldn't keep the word 'genre'. Had to change it, used (Category) instead....
Secondly, there is not a 'BLANK' or --- Select a Category --- position for the dropdown. The first title is the first category in your list. If a user does not see the category which describes their business and does not select any of those listed the first in the list will be displayed as their category.
I worked around this by creating a new category and namining it "------------". Then I add a 'desrciption' to the dropdown which states, "(Required, Please use the box below if you do not see your (category) listed in the drop-down.)"
Now, if a user doesn't see their category they can enter it into the new form field "Name Your Category". I keep this field turned off to being displayed. I have also added this 'description' "(Use this box ONLY if you did not see your (Category) in the drop-down above.)"
Then when I edit the pending listing I can create the new category.
So far so good... However, now the problem is that the new "-------" category does also show up on the Category listing page with a post count of (0).
