The <mat-expansion-panel>, an Angular Directive, is used to create an expandable detail v/s summary view.
-
<mat-expansion-panel-header> − Represents the header section. Contains summary of panel and acts as control to expand or collapse the panel.
-
<mat-panel-title> − Represents the panel title.
-
<mat-panel-description> − Represents the panel summary.
