Drop menu overlaping

Unfortunately these specific CSS queries are beyond the scope of WordPress forums. You may want to try this CSS-specific forum.

An image is totally useless when it comes to CSS — you’d need to post a link to your site. Try using Firebug to look at what is going on with the CSS. Also, be sure that you are using the position attribute with the z-index — it won’t work otherwise and that’s a common mistake.

Oh sry..here is my webs.

i tried looking up with firebug but i couldn’t make it work :S

I tried too — no luck. You have a lot of kind of convoluted code going on there… You might look at clearing up some mark-up and CSS errors on the page using the validator. Not clear if they might be causing or contributing to the menu problem.

Add this CSS;

.NWDS-nav ~ .NWDS-nav {
 z-index: 1;
}

Not working :S

Which browser and browser version are you using?
If it’s not IE6 & 7, try clearing your browser cache.

.NWDS-nav ~ .NWDS-nav {
       z-index: 10 !important;
}

Nope…still not working..
Chrome and Firefox.
I cleared cache on both..

.NWDS-nav ~ .NWDS-nav {
       z-index: 10 !important;
}

This one works for me like a charm. Please put this in your style.css

I’m not sure whether you’re using a Child Theme, but I recommend using a Custom CSS plugin to handle your CSS.

Dunno why it didn’t work but now it does xD
Thanks thats great,really working like a charm,thanks a lot ??

Awesome, have a nice weekend. Cheers!

It didn’t work before without the !important because you added it above CSS that was overriding it.

}

When you add new styles to a stylesheet, try to do-so at the bottom of the stylesheet.
