Welcome to the forum.
What is a pre-defined help file? Do you simply mean someone
else created the project? You also say you you imported the files
but it's not clear why. Maybe that does not matter, I mention it in
case the next bit is not the problem as then I will need to know
more.
It should be as simple as double clicking the drop-down
hotspot. Does nothing happen if you do that? The text should be
above the ordinary text when you look at the HTML.
