可滚动的弹出菜单
我正在尝试创建一个弹出菜单，如果它比屏幕大，则内置滚动菜单。我似乎无法弄清楚如何使用本机溢出-y 滚动属性来做到这一点。每次我似乎设置了overflow-y:auto，那么飞出的菜单就会嵌套在带有滚动条的父div中。
有人有什么想法吗？
谢谢！
I'm trying to create a flyout menu that has scrolling build in if its larger than the screen. I can't seem to figure out how to do this with the native overflow-y scrolling properties. Everytime I seem to set that overflow-y:auto then the the menu that flys out is nested within the parent div with a scroll bar.
Anyone has any ideas?
Thanks!

你应该为div设置最大高度proparty，否则它无法告诉（因为它是绝对定位的）在哪里停止，或者你可以为旧浏览器设置高度，或者你可以用javascript编写它，动态改变高度直到它达到最大
you should set the max-height proparty for the div otherwise it cant tell (since it is sort of absolutely positioned) where to stop, or u can set the height for older browsers, or you can javascript it, change height dynamically until it reaches a maximum
