我之前已经问过类似的问题，但是由于我对上一个没有任何答复，因此试图澄清得更好；）谢谢！

我在Bootstrap的“ xs”视图（汉堡按钮）中扩展了导航栏/菜单。

• 如何使导航栏/菜单扩展到100％并在需要时可滚动？

原始代码：

#menu1 .navbar-collapse{padding:0;}

使用原始代码时，菜单将打开到屏幕面积的大约50％，并且下拉菜单可滚动（很好）。

我的代码（我正在寻找解决方案）：

#menu1 .navbar-collapse{padding:0; min-height:100%}

当我尝试添加以上CSS时，什么也没发生。看起来还是一样。最低高度是怎么回事：100％不会一直将下拉范围扩大？

任何想法如何解决这个问题？

非常感谢。 /马库斯

整个菜单的CSS：

/* menu 1 - XS view */
#menu1 { background-color: #f5f5f5; min-height: 40px;}
#menu1 .navbar-collapse{padding:0; min-height: 100%;}
