I am using the Plugin 1.5.1.1 Gravity Forms with Custom Types Post Plugin UI 0.7, integrating them with the Gravity Forms Plugin + Custom Post Types 2.0 and would like to use form fields to taxonomies.
This way I can just use Drop-down, Radio-buttons or Multiple-choice fields. I wonder if can use the drop-down menu with the option of selecting more than one term. I would not use Multiple Choice, because it would be a very extensive field. (for the taxonomy in question are about 70 terms).
The perfect feature would be support to Custom Post Types and Custom Taxonomies and to insert the word through the form, with the option to autocomplete, and the menu with the terms already entered, (as when entering new categories, taxonomies or tags like the standard post form of the Wordpress Admin Panel). I saw a solution like this for the plugin TDO Mini forms at http://www.ilovecolors.com.ar/custom-taxonomies-tdomf/, but it was imperfect and insert the ID of the taxonomy instead of the name of the new term.
