+specified on the Store. The group will show the title for the group name and then the appropriate records for the group
+underneath. The groups can also be expanded and collapsed.</p>
+
+<h2>Extra Events</h2>
+
+<p>This feature adds several extra events that will be fired on the grid to interact with the groups:</p>
+
+<ul>
+<li><a href="Ext.grid.feature.Grouping.html#groupclick" rel="Ext.grid.feature.Grouping#groupclick" class="docClass">groupclick</a></li>
+<li><a href="Ext.grid.feature.Grouping.html#groupdblclick" rel="Ext.grid.feature.Grouping#groupdblclick" class="docClass">groupdblclick</a></li>

+<li><a href="Ext.grid.feature.Grouping.html#groupcollapse" rel="Ext.grid.feature.Grouping#groupcollapse" class="docClass">groupcollapse</a></li>
+</ul>
+
+
+<h2>Menu Augmentation</h2>
+
+<p>This feature adds extra options to the grid column menu to provide the user with functionality to modify the grouping.
+This can be disabled by setting the <a href="Ext.grid.feature.Grouping.html#enableGroupingMenu" rel="Ext.grid.feature.Grouping#enableGroupingMenu" class="docClass">enableGroupingMenu</a> option. The option to disallow grouping from being turned off
+by thew user is <a href="Ext.grid.feature.Grouping.html#enableNoGroups" rel="Ext.grid.feature.Grouping#enableNoGroups" class="docClass">enableNoGroups</a>.</p>
+
+<h2>Controlling Group Text</h2>
+
+<p>The <a href="Ext.grid.feature.Grouping.html#groupHeaderTpl" rel="Ext.grid.feature.Grouping#groupHeaderTpl" class="docClass">groupHeaderTpl</a> is used to control the rendered title for each group. It can modified to customized
+the default display.</p>
+
+<h2>Example Usage</h2>
+
+<pre class="prettyprint"><code>var groupingFeature = Ext.create('Ext.grid.feature.Grouping', {

+
+<p>This option is useful during Component construction to add DOM event listeners to elements of <a href="Ext.Component.html" rel="Ext.Component" class="docClass">Components</a> which

+<pre><code>new Ext.panel.Panel({
+    title: 'The title',
+    listeners: {
+        click: this.handlePanelClick,
+        element: 'body'
+    }

+<p></div></li>
+</ul><br></p>
+

+<b>Combining Options</b><br>
+Using the options argument, it is possible to combine different types of listeners:<br>

+A delayed, one-time listener.
+<pre><code>myPanel.on('hide', this.handleClick, this, {
+single: true,
+delay: 100
+});</code></pre>
+<p>
+<b>Attaching multiple handlers in 1 call</b><br>
+The method also allows for a single argument to be passed which is a config object containing properties
+which specify multiple events. For example:
+<pre><code>myGridPanel.on({
+    cellClick: this.onCellClick,
+    mouseover: this.onMouseOver,
+    mouseout: this.onMouseOut,
+    scope: this // Important. Ensure "this" is correct during handler execution
