How to Work With Tabs

Hi everyone,

is there any reference on how to work with tabs, like the example on the Webdetails
website DEMO#2 - Content 1 and Content 2 ?

How to display a dashboard on a tab and another dashboard in another tab, like the example
on the Webdetails website DEMO#1 - As "Sales Vs Gross Profit and Quantity Vs Gross Profit"?

Any hint is welcome.
Thanks and best regards.
