The Day of the Turkish Republic, Oct.29
We need a side menu, and here is one created for Vanilla. In order to edit the menu, you need to temporary give the container 'sidenav' some width, afterwards set it back to zero. There is a bit of styling and js in the Page manager, make sure you don't overlook it. It is best to save this building block as a theme, then you will need all of it, also the 'main' container, to be able to open the nav. The 'Open Navigation has been positioned fixed, so if you choose to make a one-pager, you will always see that 'hamburger' button.
