CMS list Form field

I want to be able to have a user select an item from a cms list and submit it like a form

ex. a page has a list of cms items and a user can select one and hit submit, in the forms tab it will have all the same information as the cms item plus any other fields in the form.

here’s the link to the site if it helps, its under the attendance page
