Is it possible to establish a CSS minimum width that is relative to a different element?

Is it possible to set the min-width of a submenu in CSS to be equal to that of the corresponding link in a navigation menu? I am using LESS for my styling.

<ul>
   <li>
    <a href="">Item FooBarBaz</a>
    <ul class="submenu">
        <li><a>sub1</a></li>
        <li><a>sub2</a></li>
        <li><a>sub3</a></li>
    </ul>
   </li>
   <li>
       <a href="">Item FooBarBazZipBamBop</a>
       <ul class="submenu">
        <li><a>sub1</a></li>
        <li><a>sub2</a></li>
        <li><a>sub3</a></li>
       </ul>
   </li>
</ul>

My goal is to have each ul.submenu match the min-width of its preceding anchor element. Since this width could vary for each submenu, is CSS capable of achieving this or would javascript be a more suitable solution?

Answer №1

Of course! Here is a sample illustration: http://jsfiddle.net/SeKT9/

ul
{
    margin:0;
    padding:0;
    list-style:none;
}



body > ul > li 
{
    float: left;
    position: relative;
}

ul > li  a
{
    display: block;
    margin: 5px;
}

ul > li:hover > ul
{
    display: block;
}

ul > li > ul
{
    position: absolute;
    min-width: 100%;
    background-color: green;
    display: none;
} 

ul > li > ul > li
{
    display: block;
}

Answer №2

Perhaps wrapping each submenu with an inline-block div could be a quicker and easier solution? I always hesitate to add extensive lines of code for a minor effect.

<ul>
   <li>
    <div style='display:inline-block;'>
        <a href="">Item FooBarBaz</a>
        <ul class="submenu">
            <li><a>sub1</a></li>
            <li><a>sub2</a></li>
            <li><a>sub3</a></li>
        </ul>
    </div>
   </li>
   <li>
    <div style='display:inline-block;'>
       <a href="">Item FooBarBazZipBamBop</a>
       <ul class="submenu">
        <li><a>sub1</a></li>
        <li><a>sub2</a></li>
        <li><a>sub3</a></li>
       </ul>
    </div>
   </li>
</ul>
