List of neighborhoods

I want to create a feature in my app for sellers (local stores). Each seller has to choose in which neighborhoods delivery is available depending on their current location. It has to be either on the map or in a repeating group of which the seller will choose the locations . Any idea which api will work and how

You can delimit by distance radius on the map or you can configure a list of neighborhood for seller. You can also delimit area with a group of coordinates (latitude, longitude).

How can i set up a repeating group showing the neighborhoods that are within the specified distance?

The best way do that is using the map, not a repeating group. When you get the user locations you can define the seller that delivery there. With repeating group you have to have to set at the database manually.
I help people to develop your projects. If you need some consultory to development I sent a private message with my contacts.
