+#### Coordinates and radius
+
+To pick the radius in meters as well, you have to configure the `eval.radius` option for the related radius field.
+The radius field should be a simle text input. The `default`, `minval` and `maxval` flags are passed to the geocode 
+widget so that only radius in that boundary can be chosen.
