I have three level of submenu created dynamically. I want to add class="active" where the text has the same url. A space and comma will be replaced with under score. For example, Glass, plast, gummi og porselen page will be http://www.mywebsite.com/folder/Glass_plast_gummi_og_porselen.asp Each href attribute has the same path as in URL HTML
