Dear @ChristianStudioK
yes. Sometimes things don't work instantly and you have to try things once or twice before they work. This is the price of using Wordpress :-)
Best!
Dear @ChristianStudioK
ok. I see. That makes it a bit more complex.
Then I would build a footer page and put in a thumbnail-grid without images to make the long list. As well I would do the navigation in this case manually and the site title.
Then with CSS I would place the footer as a fixed element on the left.
