드롭 다운 항목이 페이지를 벗어나지 않는 것 같습니다. BS3에서 몇 가지를 시도했지만 작동하지 않는 것 같습니다. ml-auto 때문인지 잘 모르겠습니다. (if-else 문 무시)
CodePen 은 다음과 같습니다 .

답변
Bootstrap에는 이미 내장되어 있습니다. 메뉴 정렬을 참조하십시오 . div에 dropdown-menu-right
클래스를 추가하기 만하면 dropdown-menu
됩니다.

에 대한 스타일 시트에서는 .dropdown-menu
변화 left: 0;
에 right: 0;
.
답변
인터넷 검색을 할 때이 문제를 우연히 발견했지만 react를 사용하는 사람들의 이익을 위해 (정확하지만) 수락 된 답변으로 문제가 해결되지 않습니다. React는 className에 수동으로 추가 할 때 ‘dropdown-menu-right’를 무시합니다. 대신 코드를 아래로 업데이트하면 동일한 클래스가 올바르게 설정됩니다.
자바 스크립트의 경우
<DropdownMenu right>
타이프 스크립트 용
<DropdownMenu right={true}>
이 스레드가 문제를 검색 할 때 나타나고 반응 (reactstrap)에서 부트 스트랩 4에 대한 올바른 솔루션을 알아내는 데 꽤 오랜 시간이 걸렸습니다.
답변
귀하의 코드를 살펴보고 수용된 답변이 다른 문제를 해결한다고 생각합니다. 메뉴가 페이지의 왼쪽이나 오른쪽으로 이동하고 버튼 아래에 있지 않은 경우 부모 클래스가 누락되어 있고 클래스가 잘못된 요소에있는 .btn-group
것처럼 보입니다 . 다음은 Bootstrap 4 문서의 가장 기본적인 예입니다..dropdown-toggle
.dropdown-menu
<div class="btn-group">
<button type="button" class="btn btn-secondary dropdown-toggle" data-toggle="dropdown" aria-haspopup="true" aria-expanded="false">
Right-aligned menu
</button>
<div class="dropdown-menu dropdown-menu-right">
<button class="dropdown-item" type="button">Action</button>
<button class="dropdown-item" type="button">Another action</button>
<button class="dropdown-item" type="button">Something else here</button>
</div>
</div>
코드의 작은 블록 만 살펴 보았지만 마지막에는 큰 화면에 드롭 다운이 표시되는 부분에 집중했습니다.
