I achieved this by creating a page I called Members and added it to the main Menu. I then added the links shown on the Appearance/BP Compatibility page to the menu using the Menu/Custom links box. To create a drop down I dragged the link name in the Menu box to indent it below the Members menu tab. You’ll need to enable drop down menus from the PlatformPro/Settings/Headers and Nav window.
Only the Members page was needed (although there may be another option).
