anchors and tabs

Hi there,
I’m using some buttons in my header with links included to anchors. These anchors are actually tabs. When I clink on a button that scrolls to the tabs, Id like to have the pointed tab activated and opened … For the moment all links are pointing to the tabs by default with the first tab item selected. Can you help ?
I will send you a link to the page in a second private message.
Thanks a lot for your help
