What does your option look like and what is the error?

Thanks for your reply

my option is to choose which style want addon work with.

and this is the error when i used renderCheckbox

DEBUG: cvp_style - Callback XF\Option\Style::renderCheckbox is invalid (error_invalid_method).

You might want to check the callback class to see if there is any method named renderCheckbox available.
