Where does dhtmlXMenuObject belong to?

Where does dhtmlXMenuObject belong to? I cannot find it in DHTMLX Gantt 3.1. I wanted to try what is found in demo dhtmlx.com/docs/products/dhtmlxG … onfig.html, but I do not find the included libraries in the enterprise version of DHTMLX Gantt 3.1. So what is needed additional to also have the libraries needed for that sample?

Hello
This context menu is separate independent component and you can take it from the dhtxmlSuit:
dhtmlx.com/docs/download.shtml
Simple online demos with context menu are here:
