If “Slide Up After (Px)” is enabled and the header is hidden when scrolling down on the smartphone and desktop, the body widens by x pixels and you can scroll to the right.
Hi Claudio,
Thanks for reaching out!
This looks more like an overflow issue than a problem with the setting.
Can you provide a link so I can take a look at the source code?
Best regards,

Hi timmse
I have now noticed that this happens when “Sticky on Scroll” is enabled. I’m pretty sure it’s not caused by the content if you mean that with the overflow.
Thank you!
Best regards,
Claudio
Hi Claudio,
Thanks for the link!
I guess this is caused by the language switcher, as you can see in the attached screenshot.
Please add the following custom CSS to the nav menus custom CSS field:
.brxe-nav-menu .bricks-nav-menu .sub-menu {
right: 0;
}
Let me know if this fixes the problem.
Btw, at the bottom of “Kontakt” you have negative padding on the divider, which also creates an overflow:
Hi timmse
Thanks for the overflow hint on the separator. I have adjusted that. 
After the CSS properties did not help, I have removed the language switcher from the menu. The problem still remains. And again, as a note, the problem only appears when “Sticky on Scroll” is enabled.
Hi Claudio,
what happens if you disable “Sticky on scroll”? Sticky on scroll seems to cause the problem as it adds position: sticky (sticky is always tricky). However, since the menu should not be sticky, but should slide out of the viewport, the option has no added value anyway.
If I disable “Sticky on Scroll” (I just did) then the hero area slides under the header. I have to add margin on all sites to compensate this.
But it fixes the initial problem, right? If so, we have a starting point to fix the problem 
Yes that’ s how it is. I am also aware that I can work around in that way. But the question is, is it a bricksbuilder bug or not?
Ok, we need to see if we can fix this in general.
Instead of setting a margin top on every page, you can also do that in the content tab of the theme styles:
Ok, didn’t see the content tab and added the margin there now. Thank you very much.
I can live with that for now.
Ok, let’s consider this as solved for now. I think the content margin settings is meant for exactly this purpose
Hi, I am not sure this can be considered “solved”; it just happened to me as well and I could easily reproduce it in my sandbox.
It occurs when the header is set to “sticky on scroll” and the mobile menu position is set to “Right”. The overflow scrollbar also appears for larger viewports, where the mobile menu shouldn’t be relevant anyway.
Hi Niko,
Welcome to the forum and thanks for reaching out!
I’ve tested it again with the recently released Bricks 1.5beta and cannot reproduce the issue with “sticky on scroll” and mobile menu position set to “right”. The try.bricksbuilder installation still uses Bricks 1.4.0.2. Let’s wait and see if someone reports this with 1.5beta.
Best regards,
timmse
Hi timmse,
I’m afraid it’s not solved after all.
I just tried 1.5RC2 for the first time and could easily reproduce this on a blank install.
Sample Page – Report Car Please note the horizontal scrollbar at the bottom appearing as you scroll down.
This happens when the following is true:
I think this should be investigated further and fixed.
Hi, thanks for these thread. I also have this problem.
If just “Sticky header” is checked, is works fine. But i need “sticky on scroll”, and after checking this, the scrollbar apears. Like @Claudio and @Niko_S explained.
Hope that can be fixed.
HI all. I’m having the same issue. Started building the site I’m working on in Bricks 1.5RC1 or beta (don’t remember), then updated to 1.5RC2, and now to 1.5 official release. The problem still exists.
@timmse maybe change the state from solved to… wip 
Maybe a solution?
#brx-header.sticky {
overflow: hidden;
}
This solves it! Thank you so much! I’m not sure why I haven’t tried it myself…
