在contenteditable div中获取插入符号相对于窗口的视觉位置

Question

I have contenteditable div, and I need to show a dropdown just below the current position of the caret.

For instance, if I type 'foofoofoofoo' in my div, I need to show a dropdown just below the current position of the caret which is at the end of 'foofoofoofoo'. How do I determine this position?
