[TYPO3] Breadcrumb as hierarchical <ul>

[Xavier Perseguers]

Hello,

Does someone knows how I may create a breadcrumb menu (rootline) as a 
hierarchical list:

Instead of

Home : level1 : level2 : current page

I would like to get

Home
   level1
     level2
        current page

that is

<ul>
   <li>Home
     <ul>
       <li>level1
         <ul>
           <li>level2
             <ul>
               <li>current page</li>
             </ul>
           </li>
         </ul>
       </li>
     </ul>
   </li>
</ul>
