Query Widget:  Allow selection of multiple input values in one expression

Idea created by shaver.brett on Aug 24, 2017

    It would be great if the query widget in WebApp Builder allowed the end users to select multiple results from a single expression and field (think the "IN" expression in SQL).  For example, if the user is trying to query chemical data and there are dozens of different compounds in a single field of "Chemical Name", it would be nice if the user could select a variety of compounds with little check boxes.
