GeoJSONInput

Polymorphic form input for drawing any GeoJSON geometry. Renders a Geoman toolbar with one button per allowed shape kind. Defaults to allowing Point, LineString, and Polygon.

Installation

pnpm dlx shadcn@latest add @shadmin/geojson-input

Usage

import { GeoJsonInput } from "@/components/leaflet";
 
<Create>
  <SimpleForm>
    <GeoJsonInput
      source="geom"
      shapes={["Polygon"]}
      label="Polygons only"
      defaultCenter={[48.85, 2.35]}
    />
  </SimpleForm>
</Create>;

When collection is true, persists as a GeometryCollection of every shape on the map; otherwise keeps only the most recently drawn shape.
