I am making a page about acrobatics. I want to make a menu where the user clicks on a type of acrobatics, then more menu items pop out. Then when the user clicks on one of those items a video plays.
So the user wants to see icarian backflips. He clicks on Icarian, then the icarian menu pops up. The user clicks on backflips and then a video plays in the menu. When the user clicks on backflips again the video closes. When he clicks on Icarian section again the menu collapses. I want the menu to stack vertically so it will work well on mobile portrait.
Youtube Video plays
What is the best way to do this? I want to make something I like on the first try because I have a huge amount of information to put in this menu. Thank you for your time. Your help would be greatly appreciated.
