Change Description from testarea to Combo Box

Is there a way to change the Description on the lightbox from a textarea and to a text box or a combo box? I would love to be able to use a dropdown for this field but still able to type in a description that is not available in the list.

When I try to even change it to text I receive an error message attached.

Any help is really appreciated!


Hi,
It’s required changes in the source code and I can’t do a quick demo since it appears to be non-trivial.

Possibly better solution in this case will be to hide this default lightbox section with description and create new one with type:“select”.
