Continuing the discussion from Create a new topic button disappeared : [圖片] Create a new topic button disappeared This is expected behaviour: Horizon is an opinionated theme and we removed the create-topic button from its original place (which, depending on your setup can get rather cluttered), t…

Altho, setting a z-index:1 on the sidebar-wrapper does fix the stacking context (and makes the button behave as we want). I don’t think that has any other consequences, but you never know with z-index.

You mean like this? [CleanShot 2026-08-20 at 17.13.22@2x] Something like this would work I think .sidebar-new-topic-button__wrapper { position: fixed; bottom: 2rem; right: 2rem; margin: 0; } But it won’t be “aware” of any other elements on the page, so will overlap things.

Thank you! That is what I tried, but it gets hidden by many other elements, and the tricky z-index: 999 is not working there. I understand this is because of the ancestor elements in the theme. It gets hidden by topic cards, right sidebar elements, and so on.

Hmm youre right. Oddity. Ill look why it does that

Ah it’s because it’s DOM parent has position:sticky… Okay that the reason but not sure there is a CSS solution :sweat_smile:

How do I make the button visible to users who are not yet logged in? @chapoi

Hi there, please open a new topic for this in Development and try not to ping staff members, thanks.
