Detailed Description

Stores tabs list.

Example how to print a single line tabs: $rows = array( new tabobject(...), new tabobject(...) ); echo $OUTPUT->tabtree($rows, $selectedid);

Multiple row tabs may not look good on some devices but if you want to use them you can specify ->subtree for the active tabobject.

Parameters

string | null	$selected	which tab to mark as selected, all parent tabs will automatically be marked as activated
array | string | null	$inactive	list of ids of inactive tabs, regardless of their level. Note that you can as weel specify tabobject\$inactive for separate instances
