All functionality for expanding/collapsing, selecting and interacting is implemented (and documented) with plain JavaScript at the end of the examples.

Usage
| Element | Class | Description |
|---|---|---|
.appWrapper__regions | .has-appBarAdvanced | This class is necessary for the general / overall layout to calculate (left side) whitespace for the advanced app bar . |
.appWrapper__regions | .has-appBarAdvanced .has-appBarAdvanced-collapsed | This class has to be toggled from clicking the "collapse" link in the footer section of the advanced app bar and extends the app layout for a smaller, condensed version of the advanced app bar. |
.level1 | .is-shown | This class shows the title as well as the subitems ("level2") of an app bar item. This class should be removed on mouseout of such an item again. There should never be more then one single app bar item with this class. |
.level1 | .is-active | This class expands and visually highlights the currently selected ("active") app bar item. This should be triggered on click of the App bar item. There should never be more then one single app bar item with this class. |
.item__icon | .has-notification | This class shows an indicator next to an item's icon. This can be used to indicate that something within this app's module needs an user's attention. The color of the indicator is set to the global state color used for errors (default: red). |
