z-index issue with twitter bootstrap dropdown menu

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.

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.


I had a similar issue that turned out to caused by "overflow: hidden" on a parent div. The solution was easy for me since, after reviewing it, I determined that I didn't need the overflow: hidden anymore so I removed it.
You saved my nerves. Thank you.
@ScottForsyth-MVP I skimmed past your comment thinking.. overflow:hidden - that's not my issue - mine is all about z-index. So I went to the MDN page on stacking contexts (highly recommend) and went through my site meticulously setting positions and correct z-indices. Still the menu was being cut off. Then I noticed overflow:hidden in the css inspector and it reminded me of your comment - and that was it!
Although I have a slightly different structure in the DOM and elements, what made the solution for me in the end was changing the z-index of the element that contained the dropdown element(s). Thanks!
@ScottForsyth-MVP Thanks! your comment saved my live :D

IE 7 on windows8 with bootstrap 3.0.0.

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

fixed

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.


Worked for me, no side effects.

This will fix it

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

This will cause problems with bootstrap modal dialogs, as modal-backdrop's z-index value is lower.

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.

In my case in addition to z-index I had to set overflow: visible in parents elements

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


I just increased .dropdown-menu z-index to 1001. The solution is to increase this value. Sorry for my bad english ^^
ahh .. then I misunderstood you, sorry. You might consider a slight clarification in your answer (like you did in your comment :-)

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

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

Just give

position: relative; 
z-index: 999;

to the navbar


This works for me but you don't need to set the z-index property to 999. You can set it to 2.

This fixed it for me:

.navbar-wrapper {
  z-index: 11;
}

Solved this issue by removing transform: translateY(50%); property.

.dropdown, .dropdown-menu {
  z-index:2;
}
.navbar {

  z-index: 1;
}
