title: Magento: how to write own catalog navigation render function?
body: <p>By default function Mage_Catalog_Block_Navigation->renderCategoriesMenuHtml render it.
  Now I would like to change the way catalog navigation render.</p>
  
  <p>What I should do then?</p>
  
  <p>1) write own module? - then I have to copy the same files from category module.</p>
  
  <p>2) to create own logic in a template? - it is not correct. Template haven't has a logic inside itself.</p>
  
  <p>3) Which ones then?</p>
