+ * DatePicker renders an datepicker jQuery UI widget.
+ *
+ * For example:
+ *
+ * ```php
+ * echo DatePicker::widget(array(
+ *     'language' => 'ru',
+ *     'model' => $model,
+ *     'attribute' => 'country',
+ *     'clientOptions' => array(
+ *         'dateFormat' => 'yy-mm-dd',
+ *     ),
+ * ));
+ * ```
+ *
+ * The following example will use the name property instead:
+ *
+ * ```php
+ * echo DatePicker::widget(array(
+ *     'language' => 'ru',
+ *     'name'  => 'country',
+ *     'clientOptions' => array(
+ *         'dateFormat' => 'yy-mm-dd',
+ *     ),
+ * ));
+ *```
