bootstrap 选择器下拉列表中的内联元素

Question

我的 fiddle 是 here. It is based on answers to this post。

这是一个简单的select选择器，用图标代替文本。

我希望用户能够 select 列表中的图标。但是，由于有大量非常小的图标，我想让它们在下拉列表中以二维 table/grid/matrix 显示（目前每行显示一个图标）。 table 中的列数应根据页面宽度缩放。

我把它想象成一个 simple colorpicker 图标而不是颜色。

我愿意使用不同的控件，如果不是 bootstrap-selectpicker。

Answer 1

您可以对每个下拉项应用 col-md-6（或每行任意数量），就像对任何其他元素一样。 sample

<div class="btn-group">
  <ul class="nav pull-right">
      <li class="dropdown">
          <a href="#" class="dropdown-toggle" data-toggle="dropdown">Icon x2 Menu <b class="caret"></b></a>
          <ul class="dropdown-menu" id="icons"><li class="dropdown-header">Glyphicons</li>
            <li class="pickList col-md-6 text-center" value="Icons.Glyphicons.adjust"><a href="#"><i class="glyphicon glyphicon-adjust"></i></a></li>
            <li class="pickList col-md-6 text-center" value="Icons.Glyphicons.align_center"><a href="#"><i class="glyphicon glyphicon-align-center"></i></a></li>
            <li class="pickList col-md-6 text-center" value="Icons.Glyphicons.align_justify"><a href="#"><i class="glyphicon glyphicon-align-justify"></i></a></li>
            <li class="pickList col-md-6 text-center" value="Icons.Glyphicons.align_left"><a href="#"><i class="glyphicon glyphicon-align-left"></i></a></li>
            <li class="pickList col-md-6 text-center" value="Icons.Glyphicons.align_right"><a href="#"><i class="glyphicon glyphicon-align-right"></i></a></li>
            <li class="pickList col-md-6 text-center" value="Icons.Glyphicons.arrow_down"><a href="#"><i class="glyphicon glyphicon-arrow-down"></i></a></li>
            <li class="pickList col-md-6 text-center" value="Icons.Glyphicons.arrow_left"><a href="#"><i class="glyphicon glyphicon-arrow-left"></i></a></li>
            <li class="pickList col-md-6 text-center" value="Icons.Glyphicons.bell"><a href="#"><i class="glyphicon glyphicon-bell"></i></a></li>
          </ul>
      </li>
  </ul>
</div>

Answer 2

这是一个使用 Bootstrap-Select 的示例：更改下拉菜单列表以显示 inline-block，同时删除 float。然后您可以设置宽度和您可能需要的任何其他样式。

工作示例：

$('select').selectpicker();

.bootstrap-select .dropdown-menu {
  padding: 5px;
}
.bootstrap-select .dropdown-menu > li {
  position: relative;
  display: inline-block;
  float: none;
  text-align: center;
  width: 20%;
}
@media (min-width: 768px) {
  .bootstrap-select .dropdown-menu > li {
    width: 10%;
  }
  .bootstrap-select .dropdown-menu > li > a {
    font-size: 22px;
  }
}
