Selector Usage

This is the basic selector with no content, header or hiddend content

This selector uses content projection - the following selector can be projected into the component - the element does not matter.

Content Projection Selectors

Selector header - this will project your content into the header area

<div header></div>

Selector showContent - this will project your content into the content area

<div showContent></div>

Selector hiddenContent - this will project your content into the hidden content area

<div hiddenContent></div>

Please note that is you do not provide hidden content - the actions will not appear thus displaying the card as a regular card compoent.

Here is a sample using all content projection selectors

<wav-collapsible-card>
  <div header fxFlex>
    <mat-toolbar>
        <span fxFlex class="title">Title</span>
        <button mat-icon-button>
            <mat-icon class="fade">info</mat-icon>
        </button>
    </mat-toolbar>
  </div>

  <div showContent style="padding: 16px;">
    <div fxFlex style="padding-top: 8px;">There is no configurations defined in this group</div>
