37 * `$mdSidenav` makes it easy to interact with multiple sidenavs
38 * in an app. When looking up a sidenav instance, you can either look
39 * it up synchronously or wait for it to be initializied asynchronously.
40 * This is done by passing the second argument to `$mdSidenav`.
44 * // Async lookup for sidenav instance; will resolve when the instance is available
45 * $mdSidenav(componentId, true).then(function(instance) {
46 * $log.debug( componentId + "is now ready" );
48 * // Sync lookup for sidenav instance; this will resolve immediately.
49 * $mdSidenav(componentId).then(function(instance) {
50 * $log.debug( componentId + "is now ready" );
52 * // Async toggle the given sidenav;
53 * // when instance is known ready and lazy lookup is not needed.
54 * $mdSidenav(componentId)
57 * $log.debug('toggled');
59 * // Async open the given sidenav
60 * $mdSidenav(componentId)
63 * $log.debug('opened');
65 * // Async close the given sidenav
66 * $mdSidenav(componentId)
69 * $log.debug('closed');
71 * // Sync check to see if the specified sidenav is set to be open
72 * $mdSidenav(componentId).isOpen();
73 * // Sync check to whether given sidenav is locked open
74 * // If this is true, the sidenav will be open regardless of close()
75 * $mdSidenav(componentId).isLockedOpen();
76 * // On close callback to handle close, backdrop click or escape key pressed
77 * // Callback happens BEFORE the close action occurs.
