When I use gallery layout: "default" I add different categories. Then I put them in a custom module with {os-gal-1}, set them in a position and then added them to a menu item. I click the menu and I see the images (category 1).
They show up and it starts with the first category. And I have also category 2 and 3 above the images. I can click these categories. But I cannot go back to category 1. There is no button for that above the images. see screenshot.
What do I do wrong?
