Header (and all fixed elements) only stays fixed on mobile

Bug Report:

I know this is probably part of the Pusher issues.

Currently, fixed elements on desktop will not stay fixed and will scroll. Once mobile (menu is gone), all issues are resolved.

Hi @TheDolo, hm, I didn't consider it like an issue, but you're right this needs some research for users that are interested in fixed Header. I think it's an "enhancement", not a "bug". Will try to figure out what's the problem.

Currently, fixed elements on desktop will not stay fixed and will scroll.

It's definitely a problem if the only fixed element allowed on the page is the sidebar!

Edit: if the page is too small for a scroll (no overflow), fixed elements work fine. So I'll insert a react custom scroll bar into a max height page for . now

[Metnew]

Oh, I just misunderstood your sentence, ok, I'll investigate this case with fixed elements on the page (desktop), haven't seen this problem before.

This is the culprit in semantic-ui-css module node_modules/semantic-ui-css/semantic.css starting around line:34342

/* Left Visible */

.ui.visible.thin.left.sidebar ~ .fixed,
.ui.visible.thin.left.sidebar ~ .pusher {
  -webkit-transform: translate3d(150px, 0, 0);
  transform: translate3d(150px, 0, 0);
}

pusher and fixed classes don't like the translate3d because of the co-ordinate shift it causes.

I'll look into a fix.

@TheDolo you can use <Rail> and <Portal> components if you need to render something outside the main container. Probably, it can be used as a temporary fix until the better solution. Also, maybe in your case Portal/Rail is the best solution.

[billymcintosh]

Sorry, people. Not quite had the time yet. I suppose this is just a starter, really. As Metnew said - it'll work outside the main container but some styling tweaks with margins and padding will be required.

Page structure was improved + react-headroom was added. Now anything can be fixed/statis/relative/etc. Anything supported.

[kodemi]

@Metnew it still doesn't work. Header (react-headroom) scrolls on desktop.

[Metnew]

Hm, ok, I'll take a look asap

[Metnew]

Not sure, but the possible root of the problem:

• missing overflow-x in <PageLayout> component
• transform:0(in SUI's .pushable) breaks something.

I had a project where this feature works as expected. I'll take a look more detailed later
