Is there a way to create a dynamic dropdown field? Dropdown that lists all users/pricelist etc.

Or how to add custom value to POINTER?

Did read the creating a custom field type but i get an error

You need to create a custom field type for such need. What was the error? I can see only the callstack.

To list users, you can use Pointer with Persons as the entity type. However, pricelist is not available for Pointer.
