Bootstrap 4 多选下拉菜单 [英] Bootstrap 4 multiselect dropdown

问题描述

我在很多论坛上看到，在 bootstrap 4 测试版之后，select 和 multiselect 的问题已经解决了.

I read on many forums that the problem of select and multiselect has been resolved after the beta version of bootstrap 4.

不幸的是，我无法在 (bootstrap 3) 中显示多选 (bootstrap 4).

Unfortunately I am unable to display the multiselect as in (bootstrap 3) in (bootstrap 4).

推荐答案

因为bootstrap-select 是一个引导组件，因此您需要像在 V3 中一样将其包含在代码中

Because the bootstrap-select is a bootstrap component and therefore you need to include it in your code as you did for your V3

注意:此组件仅适用于 boostrap-4 自 1.13.0

NOTE: this component only works in boostrap-4 since version 1.13.0

$('select').selectpicker();

<link rel="stylesheet" href="https://stackpath.bootstrapcdn.com/bootstrap/4.1.1/css/bootstrap.min.css">
<link rel="stylesheet" href="https://cdnjs.cloudflare.com/ajax/libs/bootstrap-select/1.13.1/css/bootstrap-select.css" />
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<script src="https://stackpath.bootstrapcdn.com/bootstrap/4.1.1/js/bootstrap.bundle.min.js"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/bootstrap-select/1.13.1/js/bootstrap-select.min.js"></script>



<select class="selectpicker" multiple data-live-search="true">
  <option>Mustard</option>
  <option>Ketchup</option>
  <option>Relish</option>
</select>
