|
|
|
23 |
* $rows = array(
|
|
|
24 |
* new tabobject(...),
|
|
|
25 |
* new tabobject(...)

* );
|
|
|
27 |
* echo $OUTPUT->tabtree($rows, $selectedid);
|
|
|
28 |
*
|
|
|
29 |
* Multiple row tabs may not look good on some devices but if you want to use them
|
|
|
30 |
* you can specify ->subtree for the active tabobject.
