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?
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.
I did this using php sessions and writing a custom functionality to filter.phtml. I set sessions with filter name which includes url and title, and wrote if session is set, then write it. So I literally manually created all links, when one filter is selected. Hope this will help someone..
