// 4) Submit your items with SetNextItemSelectionUserData() + Selectable()/TreeNode() calls.
// Call IsItemToggledSelection() to query if the selection state has been toggled, if you need the info immediately for your display (before EndMultiSelect()).
// When cannot provide a "IsItemSelected()" value because we need to consider clipped/unprocessed items, this is why we return a "Toggled" event instead.
