title: Show price layered navigation after selecting price filter
body: <p>I would like to show price filter option after selecting price filter already. So, I would like to keep all price filters, even if price filter is already selected. Is this possible?</p>
  
  <p>magento uses the layered navigation system where when u filter a category with something say price, all the other possible selection in the price disappears in that filter, so if you want to pick another price range, you have to go back to the previous page or deselect the filter. </p>
