I would like create a screen (AnguarJS, angular-material) :

```
<div layout="column">
   <div> <!-- 80% of window browser -->
      <md-list>
         <md-list-item ng-repeat="person in people">

         </md-list-item>
      </md-list>
   </div>
   <div> <!-- 20% of window browser -->

   </div>
</div>

```

When the list (md-list) is too long I would like a vertical scrollbar appear.
Thanks for your help.
