Dynamic, non-text custom fields

Is there a way to get non-text fields (multi-select drop-downs, radio buttons, check boxes, etc) stored into a CMS with Webflow? Assuming the answer is yes, is there also a way to get custom forms in Webflow to prepopulate based on stored data in Memberstack? Specifically, once a user enters their preferences in a custom form on Webflow, I want to store that data. When the user returns to the same page at a later time, I’d like to display those choices and allow the user to change their selections on the Webflow site which would add a new CMS record on submit.
