This is a component for Angular 2. Design is inspired by Material Design's component Expansion Panels.

Development is in very early stage

})
export class MyModule {}

Add Buttons to a panel

Every panel has already defined two methods, cancel and submit. In order to bind those to the buttons we define, we need to create a reference to the panel. In this example, I called it #panel and them I'm calling panel.cancel() and panel.submit().

It is possible to listen to these events with the outputs onCancel and onSubmit.

<expansion-panels-container>
    <expansion-panel (onCancel)='resetForm()' (onSubmit)='saveForm()'>
        <expansion-panel-title>
            Title
        </expansion-panel-title>
 
        <expansion-panel-description-hidden>
            Description when hidden
        </expansion-panel-description-hidden>
 
        <expansion-panel-description-toggled>
            Description when toggled
        </expansion-panel-description-toggled>
 
        <expansion-panel-content>
            Content
        </expansion-panel-content>
 
        <expansion-panel-buttons>
            <button (click)='pancel.cancel()'>Cancel</button>
            <button (click)='pancel.submit()'>Submit</button>
        </expansion-panel-buttons>
    </expansion-panel>
 
</expansion-panels-container>
