Ich versuche, etwas wie das Folgende zu erreichen.
Probleme:
Das Problem, das ich jetzt habe, ist, dass das Dropdown-Menü im Container versteckt ist, anstatt oben auf der übergeordneten Ebene zu erscheinen.
Was ich versucht habe:
Ich habe position:absolute ausprobiert und es funktioniert hervorragend, um die Liste über jedes übergeordnete Element zu legen.
Ein übergelaufenes Dropdown-Menü hingegen behält seine Position an der festgelegten Position, anstatt seinem Dropdown-Label zu folgen.
Daher ist position:relative erforderlich.
Kann jemand dazu etwas erklären?
Vielen Dank für Ihre Hilfe.

我无法复制你的 html 和 css，所以我创建了自己的 html 和 css，如果它与你的查询不匹配，请告诉我，我会调整
