Auto-generating Drop Menus from User Input

[MadManMallard]

I was hoping someone could help me with this. I am semi-experienced in coding, but I'll let you know if I don't understand something.

I want to make the drop down menus under the menu strip buttons have traits/names based on previously entered information from text boxes.

I'm trying to make a trading system for a game. So under the Trade tab, I would like it to list the names of the players that are entered manually in separate text boxes beforehand. Then, in each name, have the submenus generated by other previously entered information.

I hope this is explained well enough.

Thanks to all who reply! (If you need images, just request them)
