    Fair warning - this is a fairly radical departure from the default behavior of SelectItem so what might be required is to create your own ListGrid- or TreeGrid-based picker starting from eg StaticTextItem. This is because SelectItem has a bunch of keyboard handling and value management code based on the idea of selecting single or multiple items from a list, not a cascading selection in a tree.

    However to approach this based on customizing SelectItem:

    1. embed something in the data allowing you to know the indent of a given node and use formatCellValue() via pickListFields to render your indent

    2. use a recordClick or field.cellClick handler to implement your selection behavior

    Groups of Products in a Drop Down

    What is the best way to create groups in a select item (drop down)? Our data would look something like this:


    Such that if Group1 is selected, then Products 1-3 would also be selected. The reverse would be true (unselect Group1, then Products 1-3 would be unselected). Also, if Group1 is selected, and then Product2 is unselected, then Group1 would not be selected, but Product1 and Product3 are.

    If there is no out-of-the-box setting for this behavior, we could manually do this if we could have access to the cached data for the optionDataSource. How can I access the optionDataSource data? (getClientPickListData() only returns the display and value fields, but the optionDataSource has additional fields we can use to determine this hierarchy.)
