Question

我有此代码（这是引导程序固定的导航栏菜单）：

 q) f:{[l;w;i]sum w*l i+til 4} / w- weight, l- input list, i-current index
 q) f[x;-3 -1 1 3]@'til count x

当我的宽度为480px时，我无法在菜单中滚动（在菜单中单击“ gabinet”之后-打开子菜单后）。在桌面分辨率下，我没有任何问题。

屏幕出现我的问题： https://imgur.com/a/bRJrIWh

有人知道如何解决吗？该网站使用Bootstrap 3

Answer 1

max-height是在引导程序中指定的，因此您需要通过在CSS下面添加来覆盖它

.navbar-fixed-bottom .navbar-collapse, .navbar-fixed-top .navbar-collapse {
    max-height: 100% !important;
}
