Okay, I know questions similar to this have been asked before, but I can't find the answer to this specific one: I want to include a custom field on my sign up page, but I don't want to use the block {$additional_fields_html} because I want to be able to call the fields in specific places on the page. I know how to do that for a simple text field, but the one I want to include is a radio with 3 different options. I don't want to hard code in the field with its options because the options are updated on a regular basis, and its simplest to do that via the admin panel. How to do it?
