title: Angular Toggle Button on more than 1 line
body: <p>I want to implement a few angular toggle buttons. I don't exactly know how many, that depends on my database data. </p>
  
  <p>The buttons are shown on a sidebar, which means that only up to 3 buttons can be rendered in one line. </p>
  
  <p>Is there a way to break to a new line after e.g. 3 buttons ? Without creating a new mat-button-toggle-group ? </p>
  
  <p>Here's my code: </p>
  
  <pre><code>      &lt;mat-button-toggle-group multiple name="categories_1" ngModel aria-label="Kategorien"&gt;
          &lt;mat-button-toggle value="LOREM1_1" checked&gt;Value1&lt;/mat-button-toggle&gt;
          &lt;mat-button-toggle value="LOREM1_2" checked&gt;Value2&lt;/mat-button-toggle&gt;
          &lt;mat-button-toggle value="LOREM1_3" checked&gt;Value3&lt;/mat-button-toggle&gt;
          &lt;mat-button-toggle value="LOREM2_1" checked&gt;Value4&lt;/mat-button-toggle&gt;
        &lt;/mat-button-toggle-group&gt;
  </code></pre>
  
  <p>Thanks for your help!</p>
