## Events Handling

The following events are available in dhtmlxAccordion:

- onActive - occurs when the user clicks the left mouse button on item's heading;

- onDock - occurs when the window docked into the accordion;
- onUnDock - occurs when the accordion's cell undocked into the windows.

### Attaching Event Handler

The user can add any user-defined handler to any of the available events. To do this the user can use attachEvent() method with the following parameters:

- evName - name of the event;
- evHandler - user-defined event handler.

        dxhAccord.attachEvent(evName, evHandler);

Note: the names of the events are case-insensitive.
