Skel框架多级/下拉导航

Question

I am currently using skel framework for my basic website. I need to make the nav into multi level nav (dropdown). Is there a built in feature or Do I need to include some plugin? With my current setting, single level nav is working well, but when I nest the UL & LI tags, it breaks the page.

Answer 1

There is no support built into the skel.js or css that supports any drop down menus. You need to either incorporate a dropdown menu plugin (preferably a jQuery plugin, since you're already using jQuery) or code your own.

Answer 2

It's not built into skel, but it exists. The author of skel wrote dropotron, which adds dropdown menus to jquery and incorporates easily with the rest of skel plugins.
