Angular Material - Toggle Button

The <mat-button-toggle>, an Angular Directive, is used to create a toggle or on/off button with material styling and animations. mat-button-toggle buttons can be configured to behave as radio buttons or checkboxes. Typically they are part of <mat-button-toggle-group>.

In this chapter, we will showcase the configuration required to draw a button toggle control using Angular Material.
