PureCSS and CSS menu dropdowns - css

Question

I'm trying to use PureCSS, and get menudrop downs using CSS (rather than via either YUI or Jquery for portability reasons).
This is what I have so far:
http://jsfiddle.net/ket262p3/3/
<div class="pure-menu pure-menu-open pure-menu-horizontal">
<ul>
<li class="pure-dropdown">
Test1
<ul>
<li>Test2</li>
<li class="pure-menu-separator"></li>
<li>Test3</li>
</ul>
</li>
<li class="pure-dropdown">
Test1
<ul>
<li>Test2</li>
<li>Test3</li>
<li>Test4</li>
<li>Test5</li>
</ul>
</li>
</ul>
</div>
and:
#import url("http://yui.yahooapis.com/pure/0.5.0/pure-min.css");
.pure-menu-horizontal ul {
padding:0;
margin:0;
font-weight: bold;
width: 100%;
position: relative;
}
.pure-menu-horizontal ul li {
float:left;
position: relative;
display: block;
}
.pure-menu-horizontal ul li a {
display:block;
}
.pure-menu-horizontal ul ul {
display: block;
position: absolute;
top: 58px;
}
.pure-menu-horizontal ul li:hover > ul {
display: list-item;
left: auto;
}
I think the underlying problem may be some subtly in purecss that causes the second level menu not to display.
Ignore the extra classes - they represent earlier stages of getting this to work with YUI or JQuery.

Answer 1

You have to set the visibility of your subnavigation to visible.
.pure-menu-horizontal ul li:hover > ul {
display: list-item;
left: auto;
visibility: visible;
}

Answer 2

On further investigation it appears that a lot of the infrastructure for doing this is already built into PureCSS, but not documented very well. I replicate the solution below so that other people can find it.
The main solution is documented here: https://gist.github.com/maxbeatty/7829915
I have replicated in a jsfiddle: http://jsfiddle.net/0562cqd8/1/
The html is as follows
<!-- includes pure-min.css -->
<div class="pure-menu pure-menu-open pure-menu-horizontal">
Heading
<ul class="pure-menu-children">
<li class="pure-menu-can-have-children pure-menu-selected">
Cars
<ul>
<li>
Blue
</li>
<li>
Red
</li>
<li>
Green
</li>
</ul>
</li>
<li>
Trucks
</li>
</ul>
</div>
With CSS like this:
#import url("http://yui.yahooapis.com/pure/0.5.0/pure-min.css");
.pure-menu-can-have-children:hover {
background: #eee;
}
.pure-menu-can-have-children:hover ul {
top: 35px; /* height of menu li */
left: 0;
visibility: visible;
border: 1px solid #b7b7b7;
background: #fff;
}

Please try this css
.pure-menu ul
{
margin:0;
padding:0;
float:left;
width:100%;
}
.pure-menu ul > li
{
margin:0;
padding:0;
float:left;
list-style:none;
position:relative;}
.pure-menu ul > li >a
{
margin:0;
padding:0;
float:left;
padding:8px 4px;
text-decoration:none;
color:red;}
.pure-menu ul > li > ul
{
position:absolute;
top:100%;
left:0;
display:none;
width:200px;
}
.pure-menu ul > li > ul >li
{
width:100%;
}
.pure-menu ul > li > ul >li >a
{
padding:8px 20px;
background:red;
color:#fff;}
li.pure-dropdown:hover ul {
display:block;
}
change the color as per your requirement
