Category archive is a dead end?

[I may have used CSS to remove a button or link. I can’t use breadcrumbs because the chapter titles are so long, they end up over 3 lines and push the whole layout out of alignment.]

I have 16 categories (or chapters). Form the main docs page, the person can click to explore one chapter. But if that Chapter doesn’t meet their needs, there is no way to review the next chapter. They can only click the back button, and that’s not at all intuitive.

I thought that the “Other docs” section would meet this, they could find other chapters, but although there is a hover on the title implying a link, it doesn’t link to the category? Is there meant to be a button on these?

I have adjusted your layout, and I don’t use Elementor. My page builder won’t let me add widgets.

The page I need help with: [log in to see the link]
