Possible to autofill leads fields from information in my company's db? Should not update leads fields just fill the fields when company is entered..

Possible to autofill leads fields from information in my company's db? Should not update leads fields just fill the fields when company is entered..

There are two different requirements in Create Lead:

1)As I keypress in Company field, it should suggest list of companies from my db.(Is it even possible?)

2)When the Company name is accepted, address and other information is to be fetched from my db and merely show up on the address and other fields and still be editable. I came across another poster with autofill query but the suggested code has updateRecord(). Does it just fill or update the full entry in zoho CRM lead database.
