Hello everyone,,I'd like to disable user interaction with the rule filter in the query filter, so that the user cannot select another filed from the list.Say I have a query filter component as follow:Once the control is rendered, the user can select the Property1 rule filter, and change the filed to Property2. I would like to disabled that.Thanks !
