Add dots to tab through groups of three with jcarousel

Add dots to tab through groups of three with jcarousel

Hi all

I've seen this done on a few sites, but can't seem to find one when I need to! The Vodafone 360 site uses it, in the shop section, but you need to have an account.

Basically, the left and right arrows for the jcarousel plugin are tabbing through 3 items at a time, using the scroll: 3, functionality.

I would like to have a series of dots or something at the top, to click through each block of 3 items, and to show a selected state for which block you're in. I guess similar to External Controls:

But tabbing through groups of 3 and showing a selected state.

If anyone has seen this done and can point me in the right direction, would really appreciate your help.

Thanks
