The Drawer enables you to set its initial expanded state and change it on demand by using the available API options.
To specify the initial state of display for the Drawer, use its
expanded Boolean property. By default,
expanded is set to
false. The property supports a two-way binding and can be programmatically updated to immediately expand or collapse the Drawer.
The Drawer also exposes a
toggle method that can be used for expanding and collapsing the component. The difference of this suggested approach from the approach for setting the initial expanded state is that the
toggle method will trigger the
animation, which is specified in the configuration options of the Drawer.
