      singleFeature = FALSE)

    removeDrawToolbar(map, clearFeatures = FALSE)

### Arguments

`map` | The map widget.

`polylineOptions` | See `drawPolylineOptions`(). Set to FALSE to disable polyline drawing.

`markerOptions` | See `drawMarkerOptions`(). Set to FALSE to disable marker drawing.
`circleMarkerOptions` | See `drawCircleMarkerOptions`(). Set to FALSE to disable circle marker drawing.
`editOptions` | By default editing is disable. To enable editing pass `editToolbarOptions`().
`singleFeature` | When set to TRUE, only one feature can be drawn at a time, the previous ones being removed.

      addDrawToolbar(
        targetGroup = "draw",
        editOptions = editToolbarOptions(
          selectedPathOptions = selectedPathOptions()
        )
      )  %>%
      addLayersControl(
