Registration form

Hi everyone,I’m currently working on a Community Builder website. I’m looking for recommendations on the best modules and plugins that can really make the site appears interactive, and how to implement better registration experience. 

My questions:
1- How to make the registration form works as a step by step process?
2- How do I include  a signature field (e.g whiteboard area for drawing), in the registration form as well?
3- What are the best recommended modules. (Specially for the recent activity page which is empty from left and right positions) 

I searched internet, most available modules on JD are for J3 and not updated.

Thanks for your help!

1- How to make the registration form works as a step by step process?

Edit the Default template within CB > Plugin Management then under Layout > Registration you configure the layout used for your registration.

2- How do I include a signature field (e.g whiteboard area for drawing), in the registration form as well

We have no such field type. You'd have to create your own fieldtype plugin or if there's one for Joomla create a Joomla user component field of that type then create a field in CB with the type Joomla to utilize Joomla's user component field.
