You can create new fields from the CB Field manager backend.
Each field you create has a fieldtype (text, checkbox, drop-down, etc).

Please explore this area - it has many comments and tooltips also.

If you need more help then post back for community members to help you or you can become an Advanced or Professional member which gives you access to the detailed documentation.
