Question

我设法让div包含展开的菜单，覆盖整个视图（100vh）。我注意到很酷的动画，虽然它正在扩展，但只能工作到li内容的末尾（最后一个菜单链接），然后速度增加或者只是动画停止工作并且导航栏崩溃最终到达结束时查看端口，但不是很好。

你知道为什么吗？它是一个bootstrap javascript功能吗？你知道怎么解决吗？

我在这个小提琴中复制了代码

body {
  padding-top: 53px;
}

.pids-navbar{
  position: absolute;
  top: 0px;
  left: 0px;
  width: 100%;
  z-index: 99999;
}

.pids-navbar-toggle .pids-icon-bar {
  display: block;
  width: 16px;
  height: 1px;
  border-radius: 1px;
}

.pids-navbar-toggle {
  margin-top: 14px;
  margin-bottom: 14px;
  margin-right: 0px;
  float: left;
}

.pids-navbar-nav {
  margin: 0px -15px;
  font-weight: lighter;
}

.pids-navbar-collapse {
  border: 0px;
  height: calc(100vh - 60px);
}
.full-height {
  height: 100%;
}

我遇到了完全相同的问题，对我有用的是将ul的高度设置为100vh，而不是整个navbar崩溃的高度。查看代码：

var txt = $"<root>{text}</root>";
var xml = XDocument.Parse(txt);
var elems = xml.XPathSelectElements("//instance").Select(
    x =>
        {
            var sb = new StringBuilder();
            foreach (var le in x.Elements("label"))
            {
                sb.Append(", ");
                sb.Append(le.Element("group") == null ? string.Empty : le.Element("group")?.Value + "=");
                sb.Append(le.Element("text") == null ? string.Empty : le.Element("text")?.Value);
            }

            if (sb.Length > 0)
            {
                sb.Remove(0, 2);
            }

            return new { Instance = x, LabelString = sb.ToString() };
        });

注意：我正在使用引导程序4。
