z-index issue with twitter bootstrap dropdown menu

Question

I'm using twitter bootstrap dropdown menu in a fixed navbar at the top of my page.

It all works fine but am having issues with the drop down menu items showing behind other page elements rather than in front of them.

If I have anything on the page with position: relative (like jquery ui accordion, or a google chart) then the drop down menu shows behind it. Tried changing the z-index of the dd menu and of the nav-bar, but doesn't make any difference.

The only way I can get the menu to sit above the other content is to change the content to position: fixed; OR z-index: -1; -but both of these solutions cause other problems.

Appreciate any help you can give me.

I think this is probably some standard issue with CSS positioning that I've misunderstood, so haven't posted any code, but can do if needed.

Thanks.

Answer 1

Just realized what's going on.

I had the navbar inside a header which was position: fixed;

Changed the z-index on the header and it's working now - guess I didn't look high enough up the containers to set the z-index initially !#@!?

Thanks.

Answer 2

IE 7 on windows8 with bootstrap 3.0.0.

.navbar {
  position: static;
}
.navbar .nav > li {
  z-index: 1001;
}

fixed

Answer 3

Ran into the same bug here. This worked for me.

.navbar {
    position: static;
}

By setting the position to static, it means the navbar will fall into the flow of the document as it normally would.

Answer 4

This will fix it

.navbar .nav > li {
z-index: 10000;
}

Answer 5

I had the same problem and after reading this topic, I've solved adding this to my CSS:

.navbar-fixed-top {
    z-index: 10000;
}

because in my case, I'm using the fixed top menu.

Answer 6

Still the issue with Bootstrap v3, navbar and dropdown have same z-index ;-( I just increased .dropdown-menu z-index to 1001.

Answer 7

Solved by removing the -webkit-transform from the navbar:

-webkit-transform: translate3d(0, 0, 0);

I had the same problem, in my case because i forgot this in my NavBar style: overflow: hidden;
