+</span></span> * @class Ext.form.field.Checkbox
+ * @extends Ext.form.field.Base
+
+Single checkbox field. Can be used as a direct replacement for traditional checkbox fields. Also serves as a
+parent class for {@link Ext.form.field.Radio radio buttons}.
+
+__Labeling:__ In addition to the {@link Ext.form.Labelable standard field labeling options}, checkboxes
+may be given an optional {@link #boxLabel} which will be displayed immediately after checkbox. Also see
+{@link Ext.form.CheckboxGroup} for a convenient method of grouping related checkboxes.
+
+__Values:__
+The main value of a checkbox is a boolean, indicating whether or not the checkbox is checked.
+The following values will check the checkbox:
+* `true`
+* `'true'`
+* `'1'`
+* `'on'`
+
+Any other value will uncheck the checkbox.
+
+In addition to the main boolean value, you may also specify a separate {@link #inputValue}. This will be
+sent as the parameter value when the form is {@link Ext.form.Basic#submit submitted}. You will want to set
+this value if you have multiple checkboxes with the same {@link #name}. If not specified, the value `on`
+will be used.
