Hi Eric
I picked up both your threads, I'll reply to this one first as it is more straightforward.
You can only add a parent selector to a normal form, i.e. the "one" part of a one-to-many relationship.
If you need to add a selector for the "many" part of a relationship, well you can't. You need to use relationship forms to connect existing posts in that case (see https://toolset.com/documentation/post-relationships/how-to-build-front-end-forms-for-connecting-posts/ ).
It is a limitation of the implementation of post relationships in Toolset Forms. You might want to add your voice for bringing parity between post relationships in the back end edit screens and front-end Forms here: https://toolset.com/home/contact-us/suggest-a-new-feature-for-toolset/
If you really need a selector for the many part of a relationship in a normal form then you would need to implement it yourself, setting up the select dropdown populated by the relevant posts, and then using the cred_save_data hook (https://toolset.com/documentation/programmer-reference/cred-api/#cred_save_data ) to manually attach the posts using the toolset_connect_posts API function (https://toolset.com/documentation/customizing-sites-using-php/post-relationships-api/#toolset_connect_posts ).
