As you saw in Chapter 10, Backend Views, there’s a plethora of widgets that display your data in a certain way. To demonstrate how to create your own widget, we’ll write one that lets the user choose a many2one reference from a predefined selection of values in the form of a list of buttons. The result looks somewhat similar to the many2many_checkboxes widget, but with buttons instead of checkboxes.
