I have a form that will have SharePoint text fields to collect an address. There is a need to have a check box to say the physical address is the same as billing address. Am I able to do that using JS?
Dear @volkjr,
Absolutely! You can copy, check, modify, etc. There are almost no limitations to what you can do with JavaScript, find basic examples in this article here - Work with SharePoint form fields in JavaScript — SharePoint forms
You can also find specifics of how to work with each field here - SharePoint field types — SharePoint forms
If you have any questions or run into any issues - let us know!
