Expandable section in use

Currently, the expandable section is used in combination with several components, e.g. Tags

This Angular component provides basic expand/collapse functionality with a header. A <dt-expandable-section> element should be used whenever some action is performed. It has to contain a <dt-expandable-section-header> which contains the header content.

Animation is done using Angular animations. So, don't forget to provide the animations module, too.

@NgModule({
  imports: [
    DtExpandableSectionModule,
  ],
})
class MyModule {}
