[CSS] 處理內部元素無法完全顯示的問題，當父元素加入overflow:hidden時

之前遇到頁面上做了一個contextmenu的選單效果，但一直被顯示時，選單會因為父元素裡面設了overflow:hidde，導致這個問題。

This is an old question but encountered it myself.

I have semi-solutions that work situational for the former question("Children visible in overflow:hidden parent")

If the parent div does not need to be position:relative, simply set the children styles to visibility:visible.

If the parent div does need to be position:relative, the only way possible I found to show the children was position:fixed. This worked for me in my situation luckily enough but I would imagine it wouldn't work in others.
