I need to create a custom content section in the store admin are for use in a product locator. Inside the section, I'll have a repeating block that takes in a simple text address. When the user saves the address, it fetches the longitude and latitude via geocoding and stores it in two read-only fields. Once the values are stored I'll be able to retrieve each location to add as markers within a google map.
The problem is, I don't see any support for this type of functionality in the existing documentation. The only way I can see to do this is to hardcode it, but I'd like my client to be able to enter the addresses themselves.
Does anyone have any advice or links to resources on how I would be able to achieve something like this?
