Keep menu open after selecting a item in angular
<p>My menu is closing after I click on my <code>toggleShare</code>button. How can i prevent this. I use angularJS with Angular material</p>

<p>Here is my code:</p>

<pre><code> &lt;md-menu&gt;
        &lt;md-button ng-click="$mdOpenMenu()"&gt;
        &lt;/md-button&gt;
        &lt;md-menu-content&gt;
            &lt;md-menu-item&gt;
              &lt;md-button ng-click="toggleShare()"&gt; 
              &lt;/md-button&gt;
            &lt;/md-menu-item&gt;
        &lt;/md-menu-content&gt;
    &lt;/md-menu&gt;
</code></pre>
