Leaflet Easymap – Examples

33 |

34 | Leaflet Easymap is a Leaflet based library for 35 | integrating maps in webpages without programming. 36 | You just include the library in your web page and every html element with 37 | class leasymap will be turned into a Leaflet map 38 | (see examples below). 39 |

40 |

41 | Important: the element must have a height set 42 | (otherwise you'll see nothing). 43 |

You can change the attribution, but you should always give credit!
102 |
103 |
104 |
105 |
Include some Geojson (click on eyes and chin for popups).
106 | You can create geojson e.g. on geojson.io.
Warning: contents of the geojson file may be executed (e.g. scripts in the popup template). Be careful with files from unknown sources.
107 |
108 |
109 |
110 |
The whole geojson also can have a tooltip (visible on mouseover).
