Floating Action Button

Floating Action Button

The Floating Action Button (FAB) is the primary action button on a screen and is displayed in front of all screen content. In certain cases, the FAB can open a stack of two to five related actions (speed dial).

In DevExtreme, the FAB is implemented as a container that collects and stores SpeedDialAction components.

To display a FAB that performs a custom action, add a SpeedDialAction component to the page. Specify its onClick, icon, and hint. Other options are optional.

If you add more SpeedDialActions (as in the onSelectionChanged function in this demo), all of them are collected in a speed dial menu that can include up to five actions. In this case, the FAB opens the menu.

You can use the floatingActionButtonConfig object to change the maximum number of actions, the FAB's position, and icons in the opened and closed states.
