Question

我有一个带有下拉菜单（https://getbootstrap.com/examples/navbar/）的经典Bootstrap 3导航栏。

我希望菜单下拉列表具有屏幕高度。它有可能吗？

Answer 1

为此示例提供height属性可能对此有所帮助。适用于drop-down项目的内嵌式css。

    <ul class="nav navbar-nav">

      <li class="dropdown"><a class="dropdown-toggle" data-toggle="dropdown" href="#">Page 1 <span class="caret"></span></a>
        <ul class="dropdown-menu" style="height:100vh;">
          <li><a href="#">Page 1-1</a></li>
          <li><a href="#">Page 1-2</a></li>
          <li><a href="#">Page 1-3</a></li>
        </ul>
      </li>
      <li><a href="#">Page 2</a></li>
      <li><a href="#">Page 3</a></li>
    </ul>
  </div>
</nav>
  
<div class="container">
  <h3>Navbar With Dropdown</h3>
  <p>This example adds a dropdown menu for the "Page 1" button in the 


navigation bar.</p>
</div>

</html>

我使用此脚本来获得解决方案。

vm.slider_callbacks = { value: 100, options: { floor: 0, ceil: 500, step: 5, showSelectionBar: true, onEnd: function (id, newValue, highValue, pointerType) { vm.radius = newValue >= 500 ? 9999 : newValue; } } };

可以用CSS吗？
