Field for "select all that apply"

Incorrect! We call that a multi-select field and it's been there for well over a decade!

don't see multi-select field as an option:

My mistake, they're called List Selection fields!

well, to be honest, those aren't working in the way I was hoping.  While I can select multiple things, I have to hold down the shift key to do so.  Many people won't understand that (even if given direction).  Plus the list doesn't fold up and to have a long list just hanging there isn't very attractive on the page.

Ideally, this would work like the usual checkboxes field but be able to select more than one.

I see.. that's a bit of a different request. I'd call that 'display list selection as checkboxes'.

To achieve your goal today of multiple checkboxes, you can do that with our Dynamic CMS and custom objects and what we call 'reactions'... that's an add-on product, but if you're up for it we can show you now it's done!
