You`ll have to edit your template`s CSS acording to get look like this.

obviesly there is more then one module on this site. You`ll have to be more specific for us to help you...

Maybe you are talking about tab modul? You have great tab modul (actualy it is component )form Gavick team - you can find it here: http://tools.gavick.com/

The news like content below is I think using galery component ....
at least the nubers below looks like the ones in rs galery, however I dont know if it is possible to create content like this with it... haven`t used it yet, so you ll have check documentation

I have a problem with flash menu. I installed mod_flashmenu for joomla 1.5 (I am using 1.5.2 with legacy on) and menu apeared where it should, however buttons don`t work (buttons galerija and domov should work, they are the only ones set at the moment) and maily flash file desapears when I click on any link inside page. Modul is assigned to ALL menus, so I don`t get it.
Any ideas what is the problem, or. maybe suggestion for other modul? I despertly need a solution.
