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. It has to contain a <dt-expandable-section-header> which contains the header content.

Imports

You have to import the DtExpandableSectionModule when you want to use the dt-expandable-section. The dt-expandable-section component also requires Angular's BrowserAnimationsModule for animations. For more details on this see Step 2: Animations in the Getting started Guide.


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

Initialization

To apply the dynatrace expandable panel, use the <dt-expandable-section> element. Example:
