Custom Transfer

I am trying to create a custom transfer similar to the one that is in DHIS2 where by a user can be able so chose between fix and relative period. After installing D2 ui in my react app and following the documentation that is in ui story blocks it is telling me that Custom Transfer not found

Hi @Yambanso_Kausiwa, not all components used are directly implemented from UI components. Can you point where this component is used, then we can have a look which one you mean exactly and help you from there.

figured it out by implementing a custom left header that handling the filtering of options thank you for the response
