How to put modules together?

So webix is great and awesome!
Was able to create data listing easily,
Was able to create data entry form and update and save using REST,
Was able to create the main page layout,
Now, how to I create an application with multiple data entry form and data listing? (preferably using sidebar)
Pleasep provide a sample code on how sidebar can show my data entry form when selected from sidebar
Thanks!

A common practice is to handle onAfterSelect event in Sidebar (a sample here) and depending on your use-case
