Selection Pattern

Hi,
Am creating a custom Doctype. It has a table of items. I need to select a few items from this table and convert the selected items into a customer quotation. What would be the best way to handle this, as I havent seen a selection pattern in ERPNEXT or did I miss it?

No, selects are not a part of the standard grid, maybe you can add them.

Best to create a custom HTML widget.
