WCFM Vendor Registration

Hi Guys

I am looking for a solution to implement Conditional Logic on vendor registration form, There are some informations which i need to collect based on vendor business type.

eg: If business type is “Solo” then show Custom text Fields field 1 $ 2

Gravity form already has this feature, but I cannot use that since GF directly register user as Vendor upon form submission without going through WCFM default vendor approval flow.

Wondering is there any snippets to work around
