세로 서브 메뉴가있는 가로 메뉴를 하위 메뉴가있는 세로 아코디언 메뉴로 변환하는 방법은 무엇입니까?

Question

모바일 에서처럼 특정 창 크기에있을 때 내 메뉴가 아코디언 메뉴의 세로 드롭 다운으로 변환되도록 내 메뉴를 만들고 싶습니다. 미디어 쿼리 및 반응 형/적응 형 디자인에 익숙하지만 커서를 가져 가거나 클릭 할 때 세로로 놓기/내리기 하위 메뉴를 가져올 수 없습니다. 여기

Answer 1

Here you go

@media (max-width:600px) { 
    tr td #navmenu li { 
    width:100%; // makes each item takes up the whole screen 
    } 
    tr td #navmenu li ul { 
    position:relative !important; // removes the position absolute so that it doesn't overlap the higher up menu items 
    top:0; // puts it right next to the menu item 
    display:none; // so there is no unnecessary white space when the `li` isn't being hovered over 
    } 
    tr td #navmenu li:hover ul { 
    display:block; // shows the submenu when you hover over the higher `li`s 
    } 
} 

Answer 2

이 t 이후 모바일 레이아웃의 미디어 쿼리

#navmenu li { 
    display: block; 
    text-align: center; 
    float:none; 
} 

#navmenu li ul { 
    display: none; 
    position: relative; 
    top:0; 
    visibility:hidden; 
} 

이 뭔가를 넣어 하위 메뉴를 표시하는 방법에 대한 echnique 순수 CSS입니다 (: 보이는 : 부모와 가시성을 가져) : 지금 아무도 내가 당신을 희망 BYT

$('li.slidedown').hover(function() { 
    $(this).find('ul').slideDown(); 
}, function() { 
    $(this).find('ul').slideUp(); 
}); 

havent 한, 내 코드를 확인 우리의 어린이 메뉴가 표시가 없기 때문에, 우리는 JS/jQuery를 필요
