html - Tailwindcss 下拉元素飞到屏幕边缘而不是在下拉按钮下方

Question

所以我正在使用 Rails、Vue 和 TailwindCss 1.0+ 制作应用

目前我正在尝试为我的产品制作一个下拉菜单，但是当我点击下拉按钮时，包含我的元素的下拉菜单飞到了屏幕的边缘，而它应该在我的按钮下面。

我不太确定哪里出错了。

问题图片:

这是下拉菜单的样子:

<!-- Start LG Products Dropdown -->
  <div class="hidden lg:inline-block">
    <button @click="prodOpen = !prodOpen" role="button" class="relative z-10 inline-block select-none focus:outline-none text-base font-normal text-blue-600 hover:text-green-600 header-font focus:text-green-600">
      <i class="fal fa-sitemap"></i><span class="ml-1">Products</span>
    </button>
    <button v-if="prodOpen" @click="prodOpen = false" class="fixed inset-0 bg-black opacity-25 h-full w-full cursor-default"></button>
  </div>
  <div v-if="prodOpen" class="absolute left-0 mt-5 bg-white rounded-lg shadow-xl w-40 headerFont text-base font-normal">
    <slot name="dropdown-items"></slot>
  </div>
<!-- End LG Products Dropdown -->

这是整个导航组件的代码:

<template>
  <nav class="flex items-center justify-between flex-wrap bg-white p-6 w-full fixed">
    <a href="https://loadze.com">
      <h1>

          <span class="font-bold text-3xl tracking-tight"><i class="far fa-truck-loading text-2xl"></i>LOADZE</span>
        </div>
      </h1>
    </a>

    <div class="block lg:hidden">

我没有完全理解您的问题。但是，如果我看到屏幕截图，我想这就是您所说的对齐方式。基于这个结论。

如果是这种情况，您必须更改以下内容:left-0 到 right-0。

<div v-if="prodOpen" class="absolute left-0 mt-5 bg-white rounded-lg shadow-xl w-40 headerFont text-base font-normal">
    <slot name="dropdown-items"></slot>
</div>

收件人:

<div v-if="prodOpen" class="absolute right-0 mt-5 bg-white rounded-lg shadow-xl w-40 headerFont text-base font-normal">
    <slot name="dropdown-items"></slot>
</div>

这将使 div 从右到左对齐，如果它扩展/需要更多空间，它将扩展到屏幕中间。
