Adding more input items at sign up

Noob here.

I’m making a board where I want to list paid profiles. Will be made in Webflow.

I need 2 simple things.

  1. After pressing the ‘sign up’ button to go to a login page with 8-10 fields.

The usual: username, password, email address
And: 3 more text fields, 1 url, 1 picture upload

In a senses something like… or

  1. After logged in the user only needs to be able to access the account details to possibly alter these inputs.

It’s important that the sign up page is clear and has all the inputs. Can I make this all go through Memberstack OR do I need an Airtable integration also to capture the url and picture upload?

Again, noob here. Just figuring stuff out. Any help is appreciated.
