I know the BeTheme and there you can set the menu to many different positions and looks…like:
- at the top
- below a header area and the snapping to the top when starting to scroll
- overlaying the whole screen
- split menue one top left, one top right
…is there a separate WP-plugin which can all these things and with every Theme?
(Especially the second one “below header area and then snapping to the top” might be complicated…because different themes handle header areas differently.)
