Can you tell me how to do a top menu with 3 strokes like you see in the smartphone version menu?
If you are referring to a button that looks like this:
Its called a Hamburger menu.
Add a Navigation bloc to your page. From the lefthand layer tree, select the “Nav Toggle” item. On the right of the screen under the visibility options, click on the devices that you wish the hamburger menu to appear on.
Thanks a lot…
