Actually, with regards to the above about PRODUCTS_OPTIONS_TYPE_GRID, I've submitted an updated copy of Product Attribute Grid to have the grid product type established/set so that it will work with Edit Orders. This means that only PRODUCTS_OPTIONS_TYPE_SELECT_SBA needs to be addressed. I will be submitting a request to edit orders to add that attribute type to the program. An unfortunate alternative is to work through all of the javascript that might be needed in order to visually support the option(s). While that is desirable it would/will take a bit of time to implement considering how edit orders handles/displays attributes far differently than how the ZC store front does.
