 # GeoJSON popup and tooltip
 
+The standard `GeoJsonPopup` and `GeoJsonTooltip` classes work well with most geometry types, but have limitations with MultiPoint and other complex multigeometries. For these cases, consider using the `on_each_feature` parameter for custom handling. See the [doc](https://python-visualization.github.io/folium/latest/user_guide/geojson/geojson_advanced_on_each_feature.html) for more information.
