I’m almost there. I used PageBuilder widget with one row in the header, in which I inserted a RichText Editor widget (both SiteOrigin) and I set up the row to be full length. I did what you suggested and the text is played out like I want it and in line with the logo.
Now if I could only move the logo to the left, in line with the first menu item. I set it up to go align to the left, but it doesn’t work.
