I want to display the question and answer in the following way. When
the user moves his mouse to one question, the question will be expanded
to show detailed answer of that question.
For example,
1. What is UML?
2 How to implement it?
3 What is the advantage of UML?
When i move the mouse to the Question 1, the question will be expaned
and have a detailed answer of it; if i don't move to there, the
outline won't expand.
I search for a long time, but have no clue.
What functions should be use???
thanks!
