Hi,

We don't offer integations with those, but you can use buttons with link to chosen plan.

It should work this way. So first create plans in your extra component, add to menu, copy link and use it here

With which components like that do you have a direct integration? Thanks

With any that you can generate links to single plan/subscription. But it's not question for me this time, but payplans or membership pro developer.

So if i want more complex forms i have to use the tables given from the extensions? There is no way to have different in SP builder?

Probably yes, you can just add custom CSS for those views.

It depends on you and your skills.
