How make autofill text fields from lookup on the portal Entity Form?

Hi all!

I'm using Microsoft portal v8, and CRM online 2016. I want to make autofill data from the selected lookup field on the Entity Form.

For example: 

i have a lookup on the form as the contact and 3 text fields: name, email, telephone. Is there possible to get FullName, Email and Phone from this selected lookup field ?

Thanks in advance!
