The new Cassiopeia template comes with a lot of module positions.
We have created an image for you to have them all visualised. We have set up to 4 horizontal positions in Top-A, B, Bottom-A and B, but this can be set to your needs. And with some css you can set the Logo, menu and search on 1 line.
Note: these are the default template module positions. With css alterations we can create the option to have the logo / menu / search in 1 line, and use a topbar, that is placed above the logo bar.
