Modification & Customization - HomeBuilder in Openhab 2.0

Hello,

I wanted to modify the Openhab homebuilder that is documented here - https://www.openhab.org/docs/configuration/homebuilder.html.

I actually followed the instructions that is described here:
https://github.com/openhab/openhab-core/tree/master/bundles/org.openhab.ui.homebuilder, but how to exactly “When you’re done with your changes

There was no specific instructions on how to modify this page. I was trying to do this modification through web console but that did not help.

So, How to exactly modify this vue.js page? Could you provide a sample/demo of any single modification?

My objective is to customize this home-builder with specific available items and specific rooms.

Thanks,
Sundar.
