This is Kendo UI for MVC
OK, so let's assume we have two makes and two models, like this
Makes: Ford, Chevy
Models: (Ford, Pinto), (Ford, Fiesta), (Chevy, Silverado), (Chevy, Citation)
I want to have a data grid. On that data grid, there will be an 'Add' button. Each time that add button is clicked a new row is added to the grid, and the user chooses a make and a model.
After adding all their makes and models the user hit a big GO button and the whole smash is sent to the server to be saved.
