This members-only tutorial provides the steps to register a custom condition using which elements in Oxygen can be set to be output only if the currently logged in user belongs to the selected membership level when using WishList Member.
To check against multiple membership levels, condition type can be set to OR.
Both == and != operators are made available meaning, it is possible to output elements based on whether the current logged in member belongs to or does not belong to the selected membership(s).
