【问题描述】:
我在尝试设置下拉列表的位置时遇到问题。我希望它在一切之上,但是当它进入相对定位的元素时,它就在它后面。这是我的意思的代码示例。
html 示例:
<div class="dropdown relative">
<button class="bg-gray-300 text-gray-700 font-semibold py-2 px-4 rounded inline-flex items-center">
<span class="mr-1">Dropdown</span>
<svg class="fill-current h-4 w-4" xmlns="http://www.w3.org/2000/svg" viewBox="0 0 20 20"><path d="M9.293 12.95l.707.707L15.657 8l-1.414-1.414L10 10.828 5.757 6.586 4.343 8z"/> </svg>
</button>
<ul class="dropdown-menu absolute hidden text-gray-700 pt-1">
<li class=""><a class="rounded-t bg-gray-200 hover:bg-gray-400 py-2 px-4 block whitespace-no-wrap" href="#">One</a></li>
<li class=""><a class="bg-gray-200 hover:bg-gray-400 py-2 px-4 block whitespace-no-wrap" href="#">Two</a></li>
<li class=""><a class="rounded-b bg-gray-200 hover:bg-gray-400 py-2 px-4 block whitespace-no-wrap" href="#">Three is the magic number</a></li>
</ul>
</div>
<div class="dropdown relative">
<button class="bg-gray-300 text-gray-700 font-semibold py-2 px-4 rounded inline-flex items-center">
<span class="mr-1">Dropdown</span>
<svg class="fill-current h-4 w-4" xmlns="http://www.w3.org/2000/svg" viewBox="0 0 20 20"><path d="M9.293 12.95l.707.707L15.657 8l-1.414-1.414L10 10.828 5.757 6.586 4.343 8z"/> </svg>
</button>
<ul class="dropdown-menu absolute hidden text-gray-700 pt-1">
<li class=""><a class="rounded-t bg-gray-200 hover:bg-gray-400 py-2 px-4 block whitespace-no-wrap" href="#">One</a></li>
<li class=""><a class="bg-gray-200 hover:bg-gray-400 py-2 px-4 block whitespace-no-wrap" href="#">Two</a></li>
<li class=""><a class="rounded-b bg-gray-200 hover:bg-gray-400 py-2 px-4 block whitespace-no-wrap" href="#">Three is the magic number</a></li>
</ul>
</div>
</div>
css:
.dropdown:hover .dropdown-menu {
display: block;
}

无论如何,我如何确保列表高于一切?我尝试使用 z-index 但没有帮助。
