Parent view-> Jquery -> controller-> popup Child view(floating form) -> Submit data($tmp array variable) to Parent View

[eluser]zrowcrypt[/eluser]
Can someone help me the concept/flow/pseudocode to achive this?

1. Basically there is a page(View) that has a button (Add).
2. On clicking add, a new floating page should open that allows user to select items from a list.
3. The folating view has another button which says OK.
4. When OK is pressed the selected list of items should go back to the parent view.
5. From there I can continue with my logical CI MVC flow but I am not able to understand how 1-5 will work?

Please help me out.
