/**
* Renders a drop-down list.
* The selection of the drop-down list is taken from the value of the model attribute.
* @param array $items the option data items. The array keys are option values, and the array values
* are the corresponding option labels. The array can also be nested (i.e. some array values are arrays too).
* For each sub-array, an option group will be generated whose label is the key associated with the sub-array.
* If you have a list of data models, you may convert them into the format described above using
* [[ArrayHelper::map()]].
*
* Note, the values and labels will be automatically HTML-encoded by this method, and the blank spaces in
* the labels will also be HTML-encoded.
* @param array $options the tag options in terms of name-value pairs.
*
* For the list of available options please refer to the `$options` parameter of [[\Leaps\Helper\Html::activeDropDownList()]].
*
* If you set a custom `id` for the input element, you may need to adjust the [[$selectors]] accordingly.
*
* @return $this the field object itself
