Customize the skin

I have added a skin file Addons/Skin/s1/mod_collapse_skin.php. There you will find a replacement of original function CatHeader_Expanded(...). The new function adds the little image to the header of each category, so we can collapse the category by clicking on it.

You can modify this file and copy it into the skin folder ./Skin/sx. Do not forget to run a Resynchronize via ACP.

By default the little image is positioned left of the category name and the functions are reversed: A click on the image opens the category, a click on the name toggles between Show and Hide.
