下面是我的片段，正如您在下拉菜单中看到的那样，它的宽度很大所以我想让它的宽度等于父触发按钮，任何人都知道如何制作它？

只需覆盖下拉菜单的默认min-width：

＆＃13;

.downloadoptions {
    min-width: 0 !important;
}

<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.5/css/bootstrap-theme.min.css">

<script src="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.5/js/bootstrap.min.js"></script>
<div class="dropdown">
  <button class="btn btn-default dropdown-toggle" type="button" id="dropdownMenu1" data-toggle="dropdown" aria-expanded="true">
    test
    <span class="caret"></span>
  </button>
  <ul class="dropdown-menu dropdown-menu-right downloadoptions">
    <li role="presentation"><a class="tbcopy" role="menuitem" tabindex="-1" href="#">COPY</a>
    </li>
    <li role="presentation"><a class="tbpdf" role="menuitem" tabindex="-1" href="#">PDF</a>
    </li>
    <li role="presentation"><a class="tbcsv" role="menuitem" tabindex="-1" href="#">CSV</a>
    </li>
    <li role="presentation"><a class="tbexcel" role="menuitem" tabindex="-1" href="#">EXCEL</a>
    </li>
    <li role="presentation"><a class="tbprint" role="menuitem" tabindex="-1" href="#">PRINT</a>
    </li>
  </ul>
</div>

Answer 2

试试此代码

dropdown-menu { 
 width: 69px;
  padding: 5px 0;
  margin: 2px 0 0;
  font-size: 13px;
  }

尽量减少bootstrap 3下拉菜单的宽度
