I'm coding a graphic menu that consist in five divs with a background each. On mouseover the background changes and the child div disappears. On click, each one works like a link to the correspondent category. I want to apply some changes to the clicked div, so I was wonder if there is some function in wordpress to get the selected category. So I can check for It and in function of wich category is selected apply the changes to the correspondent div.
Thanks in advance.
