<li class="task-list-item"><input type="checkbox" id="" disabled="" class="task-list-item-checkbox" checked=""> I have searched the <a href="https://github.com/callemall/material-ui/issues">issues</a> of this repository and believe that this is not a duplicate.</li>

<h2 dir="auto">Expected Behavior</h2>

<p dir="auto">When list is long in Dialog, it should have vertical scroll bar in dialog. This works well in Chrome and Firefox.</p>
<h2 dir="auto">Current Behavior</h2>

<p dir="auto"><a href="https://material-ui-1dab0.firebaseapp.com/demos/dialogs/" rel="nofollow">https://material-ui-1dab0.firebaseapp.com/demos/dialogs/</a> the Confirmation Dialogs demo.<br>
when open in ie 11, the vertical scroll bar doesn't work. it lists all items which push buttons out of page.</p>

<h2 dir="auto">Context</h2>
    
<p dir="auto">I think categorizing the components by use case, something like what <a href="https://ant.design/docs/react/introduce" rel="nofollow">Ant design</a> are doing with having navigation, data entry, data display categories etc. will be a nice improvement for having an easier time getting through the list of component demos/API.</p>
