CSS Question

CSS3 multi-column list

I've been using CSS3 multi-column for a few Wordpress sites now and one thing that I find excepteble but still something I want to know how to fix is that if I put a list(with sub items) in the collumns that it won't keep the structure of the list

To make myself clear this is the HTML:

<div>
<ul>
<li>
List-item
<ul>
<li>Sub-list-item</li>
<li>Sub-list-item</li>
</ul>
</li>
<li>
List-item
<ul>
<li>Sub-list-item</li>
<li>Sub-list-item</li>
</ul
</li>
</ul>
</div>


And the CSS would be:

div{
-webkit-column-count:3;
-moz-column-count:3;
-ms-column-count:3;
-o-column-count:3;
column-count:3;
-webkit-column-gap:15px;
-moz-column-gap:15px;
-ms-column-gap:15px;
-o-column-gap:15px;
column-gap:15px;
columns:3;
}


And this is what you get:

This is nice because it makes it possible in Wordpress to show menu's like this.
But one thing that bugs me is that it places the Sub-list-items in the next column while the parent of that item is in the previous column.

Is this fixable?

Before anyone says: why don't you just make multiple lists and make your own columns(this was the suggestion when I asked the question how to do this) this is for a dynamic Wordpress menu so I have no controll over how many items are in the menu.

Answer

Making your parent <li> display: inline-block; seems to "fix" this:

Here is a demo http://jsfiddle.net/DczVL/1/

ul {
    list-style: none;
    margin:0;
    padding:0;
}
ul > li {
    display: inline-block;
    width: 100%;
}
ul > li > ul >li {
    color: red;
}
div {
    -webkit-column-count:3;
    -moz-column-count:3;
    -ms-column-count:3;
    -o-column-count:3;
    column-count:3;
    -webkit-column-gap:15px;
    -moz-column-gap:15px;
    -ms-column-gap:15px;
    -o-column-gap:15px;
    column-gap:15px;
    columns:3;
}
<div>
    <ul>
        <li>List-item
            <ul>
                <li>Sub-list-item</li>
                <li>Sub-list-item</li>
            </ul>
        </li>
        <li>List-item
            <ul>
                <li>Sub-list-item</li>
                <li>Sub-list-item</li>
                <li>Sub-list-item</li>
                <li>Sub-list-item</li>
            </ul>
        </li>
         <li>List-item
            <ul>
                <li>Sub-list-item</li>
                <li>Sub-list-item</li>
                <li>Sub-list-item</li>
                <li>Sub-list-item</li>
            </ul>
        </li>
    </ul>
</div>
