Hello,

I've got a problem which I cannot find the solution for.
My site has a following layout:

---

---

| article1 | | category1|
| article2 | | category2|
| ...... | | ....... |
__________________

---

When the user chooses any Category I want to apply filter on articles. But the list of Categories must remain the same with selected Category highlighted (the same as menu generally works).
Now after selection of Category it drills down and show only one selected (the article filter is OK).

I thing it's a general way of workflow for many sites but I cannot figure out how to do this.

Many thanks in advance for helping,
Alex.
