I have imported a video as an event video into a fluid box. 

Now, i need to place a next button in the same fluid box. What is the procedure to do so?

You cannot stack objects in a normal fluid box. Which means you cannot put a button on top of an event video in a normal fluid box, you need to create another fluid box for that.
