This website has a simple structure, where you have tabs for each section of the website. As shown below you have each main tab:
As you can see the Support tab has become blue, this means that we are currently under the Support tab. Try changing to another tab, and see that it now shows another tab you are under^^
On some tabs you can see that when you click it a dropdown menu will be shown, this is under categories which is related to the main tab.
