Populate form with previous data

I'm looking to add a feature to my application which currently, you enter your first name and last name and a few other details.

What I want to add is the ability to start typing the first name in the form and instantly output those with a similar name and if the name is there then use those details rather than entering the name again.

Once you've selected the name of a previous entry you can carry on adding the data to the form for the fields not populated.

I'm currently working with laravel any insight to tackling this one would be greatly appreciated.

Thanks
