## Side navigation

### Mode

The side navigation has two modes: the standard mode with a two-level navigation and the extended mode with a three-level navigation. Extended mode is activated automatically if the navigation contains three levels.

You can switch to extended mode in the demo application by clicking on the extended mode.

### Overlay

Navigation items can have overlays instead of router links. You can use existing overlay components (LogoutComponent) or create custom overlays with the content you need.
