Create grids at runtime help

I’m wanting to create an app to organise teams of drivers and their agricultural machinery. I’d like a whiteboard look with ‘floating’ teams, displayed in a standard grid control,which the user can drag anywhere on the screen and drag and drop drivers on to the grid.

My question is can I create these ‘team’ grids programatically at run time when the user adds a new team? Or do I need to have the number of grids I could potentially need created at design time?

I would suggest looking at a drag and drop kanban js library - that will probably deliver what you need
