Template for Online Submission - Membership Application

[Duckdown]

Any suggestions for free templates that I could edit to create such a form?
I created a site for a community group and they would like the facility to Submit Membership Applications.
I designed it in MS Word and converted to PDF when they were considering just using a printed format.

I don't understand the relation to templates. You need a Forms Extension.

You could use any web-form extension (build your own forms to your specifications).

I use Convert Forms, but there are others of course. See https://extensions.joomla.org/tags/forms/

Are the members going to Register as a Joomla User?

You can use the Joomla User Registration and add Custom Fields.
