Information on the outdated Query Builder v.7.2
A different Query Builder widget was used in the previous Webix versions. Starting from version 7.3 it was replaced with a completely new one. All the users of the Webix Pro package may still utilise the old version and get technical support.
You can download the previous version of the widget in the client area.
Documentation of the outdated Query Builder widget is still available here.
The Webix team highly recommend using a new version of the Query widget as the development and technical support of the previous Query Builder will soon be suspended.
