Modification & Customization - HomeBuilder in Openhab 2.0


I wanted to modify the Openhab homebuilder that is documented here -

I actually followed the instructions that is described here:, 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.
