Style Options?

The plugin is great for displaying brands from A-Z, my only problem is that I have many brands in my store and for me it would look better not to display all brand names at once on one page.
Can someone please give me a hint, maybe with css or is there an ajax plugin out there which can convert this hmtl anchors to something like… “display on click”?

I would like to start the page with the navigation at the top, blank or with only “A” brands, when I click on B, only “B” brands can be seen and so on. Like some tabbed navigation.
