Screen shot of Layers in my current LO project. I have watched a tutorial on "pages and layers" in Layout several times but this Layers page still is a complete mystery to me. I understand the concept of "layering", however I feel like this thing has a mind of its own. I am missing a crucial piece of understanding in this puzzle.
Not sure how one layer gets attached to a page, or unattached.
The right column that has the icon of a single or multiple pages: You click it to toggle between the two. In that screen shot, you have two layers "unique elements" and "on every page" set to be on every page. Any entity that is drawn or copied to those layers will appear on every page in the file.
You can actually set every layer to be on every page if you like. Then you control each page by visibility only. I do this to certain layers if I want to quickly reference something from another page. An example would be site plans. I set a contour lines layer to be on every page, but I don't necessarily want to print contour lines on every page. In that case, I just use the eyeball to control each page.
