Tab panel opened by default

If you need a tab to be opened by default, it is possible, using data-selected="1" on the .js-tablist__link you need to be opened (See the demo, second example).

Other tabs are still available, here are the rules for this feature:

• The fragment detection (explained below) will always have priority on this feature;
• If there are several data-selected="1" put on tabs in the same group (which does not make sense and should never happen), the first one will be used.
