[Plugin: WordPress Form Manager] Categorie option in the form

Hallo Mr. Hoffcamp,

I am still using your plug-in for a school project. And it’s working great.
A little tricky at some points but all is well.

I have a new question.
As you know it is only possible to choose a catagorie in the advanced section of the form editor when you use a form as a post.
But is it perhaps possible to let users choose a categorie in the form instead of having to make the choice in advance. I know this function is not built in the editor. But perhaps there is kind of workaround?

Thanks in advance.
