Hilla with react Grid

by this grid with selection column will show but its just showing dummy check boxes if i select the item through checkboxes, the check box checked but actually item not selected.

You need to add onActiveItemChanged event listener, see example here hilla-v2-demo/frontend/views/todo/ContactDialog.tsx at master · TatuLund/hilla-v2-demo · GitHub

My Grid there is single selection, but as you see the value is an array of items

There os an another good example here Grid | Components | React | Hilla Docs
