datafilter widget in collection

Hello,

Yes, but not directly. Data Filter generates a Query object, which you can pass to the server side to use in services like QueryImplementingThings. The output of those services (an INFOTABLE object, which is essentially a grid of values) is then used as an input for Collection widget. So you can use those two widgets together, but you need to do it via a service, which takes a QUERY as an input, and outputs an INFOTABLE.
