Address Autocomplete PCF Control (Nominatim – OpenStreetMap)

The Address Autocomplete PCF Control enhances Dynamics 365 Model-Driven Apps by providing instant, intelligent address suggestions powered by the Nominatim (OpenStreetMap) API.
As users type into the address field, the control retrieves real-time location matches, allowing quick selection and automatic population of address fields — improving accuracy and reducing manual input.
