I think it would be super awesome to be able to export the Designer facing CMS Form that we use to populate CMS Collections and allow us to use those templates for user form submissions on our website.
It doesn't need any logic/functionality built into it beyond being a replica of what we see as designers in the CMS Collections. (Example image below)
I could picture it as a category of "element" that you can drag and drop into your webpage, organised by CMS Collection name.
If the CMS Collection has multireference fields or reference fields, it would be an added benefit if webflow automatically populated the options based on what field the reference field is linked to.
