More option is composed of the toggle(cue button) and more option view, and more option can change a visibility through the toggle. 
More option is based on elm_panel, but more option is different from elm_panel in that the former does not set the scrollable option. To show the more option view, select the toggle or manually use eext_more_option_opened_set(). To hide the more option view, trigger the back event or manually use eext_more_option_opened_set(). Additionally, the toggle disappears when more option view appears. On the other hand, the toggle appears when more option view disappears. The more option view can be manually set by eext_more_option_opened_set() API. An item of more option object can be selected by rotary event.
This widget emits the following signals: 
- "item,selected": When the user selects an item. 
 
- "item,clicked": When the user selects the already selected item again or selects a selector. 
 
- "more,option,opened": When more option view is shown. 
 
- "more,option,closed": When more option view is hidden.
