+ * @extends Ext.form.field.Base
+ * &lt;p&gt;A basic hidden field for storing hidden values in forms that need to be passed in the form submit.&lt;/p&gt;
+ * &lt;p&gt;This creates an actual input element with type=&quot;submit&quot; in the DOM. While its label is
+ * {@link #hideLabel not rendered} by default, it is still a real component and may be sized according to
+ * its owner container's layout.&lt;/p&gt;
+ * &lt;p&gt;Because of this, in most cases it is more convenient and less problematic to simply
+ * {@link Ext.form.action.Action#params pass hidden parameters} directly when
+ * {@link Ext.form.Basic#submit submitting the form}.&lt;/p&gt;
+ * &lt;p&gt;Example:&lt;/p&gt;
+ * &lt;pre&gt;&lt;code&gt;new Ext.form.Panel({
+    title: 'My Form',
+    items: [{
+        xtype: 'textfield',
+        fieldLabel: 'Text Field',
+        name: 'text_field',
+        value: 'value from text field'
+    }, {
+        xtype: 'hiddenfield',
+        name: 'hidden_field_1',
+        value: 'value from hidden field'
+    }],
+
+    buttons: [{
+        text: 'Submit',
+        handler: function() {
+            this.up('form').getForm().submit({
+                params: {
+                    hidden_field_2: 'value from submit call'
+                }
+            });
+        }
+    }]
+});&lt;/code&gt;&lt;/pre&gt;
+ * &lt;p&gt;Submitting the above form will result in three values sent to the server:
+ * &lt;code&gt;text_field=value+from+text+field&amp;hidden_field_1=value+from+hidden+field&amp;&lt;br&gt;hidden_field_2=value+from+submit+call&lt;/code&gt;&lt;/p&gt;
+ *
  * @constructor
  * Create a new Hidden field.
  * @param {Object} config Configuration options
- * @xtype hidden
+ * 
+ * @xtype hiddenfield
