How to add input based on single choice selection?

Do you have any input tools where i could select a company name from a drop down and then have it auto-populate an address?  There would be 3 options in the dropdown and I'd like it to populate Address, City, State and Zip based upon the selection made.  i'd prefer not to make these all separate fields, if possible, meaning that I'd like to use a configurable list widget or some other tool, if possible instead of making address, city, state and Zip individual fields.

Here is a demo form I have created to show how to do it: https://form.jotform.com/82108100572950 you can clone and edit it as required.

To achieve what you require;

1. Add a Long Text Input Field to the form below the company selected field.

2. Assign Calculation Values to Company select field. In this case, the calculation value will be the addresses. Refer to this guide: https://www.jotform.com/help/301-How-to-Assign-Calculation-Value

Add conditions to populate the Long Text Input Field with the Address of the company selected:

this is great, thank you.
