구시대의 유물인  풀다운 메뉴(pulldown menu) 입니다.

참고.

https://github.com/codrops/Blueprint-HorizontalDropDownMenu/blob/master/js/cbpHorizontalMenu.js

https://tympanus.net/codrops/2013/03/05/horizontal-drop-down-menu/

https://codyhouse.co/gem/mega-dropdown

10년쯤 묵은 코드인데 이제서야 개선할 실력이 되었네요.

참고한 소스중에 사라진 분도 계시고...

소스부분을 수정하면 정상적인 동작이 안될 가능성이 아주 많습니다

분석을 먼저 하신 후에 사용 바랍니다.
