<optgroup>

I've just found a useful HTML element that I hadn't come accross before: <optgroup>.

It's used in drop-down lists in forms to create categories that aren't selectable, for example:

<select>
  <optgroup label="Odd">
    <option value="1">One</option>
    <option value="3">Three</option>
    <option value="5">Five</option>
  </optgroup>
  <optgroup label="Even">
    <option value="2">Two</option>
    <option value="4">Four</option>
    <option value="6">Six</option>
  </optgroup>
</select>

would give:

So, hours of endless fun and entertainment...
