The following are the current Style Menus from the Squarespace Design Themes available in Squarespace v6 (currently in private beta). The templates are in continuous flux and new options are added sometimes on a daily basis. I’ll try to keep up with the changes but there are no guarantees these are 100% accurate. If you notice a change before I do, please keep me updated in the comments and I’ll update the page ASAP.
If you would like to get on the beta list, check out the Beta FAQ Page.
