Select company name from dropdown, autofill company address in text field
I'm designing a form for work. I've made a drop down box containing the names of different Cellular Providers and I'd like to associate that drop down list with a text field where the selected company's mailing address will auto populate.
For example, some of the options in the drop down are; AT&T, , T-mobile & Verizon.
So if the form user selects AT&T from the dropdown, I'd like for the text field to automatically populate with
AT&T Operational Headquarters
11760 US Hwy 1,
N. Palm Beach, FL 33408
selecting C spire would populate;
Corporate Security Telapex, Inc
1018 Highland Colony Parkway, Suite 500
Ridgeland,MS 39158
and so-on.
Surly there is a way, I just can't find mine.
Thanks in advance
