Ideas and Suggestions for Leaflet

Leaflet UserVoice is a place for you to show support for your favorite feature and improvement suggestions for Leaflet.

  • Please don’t add duplicates of existing ideas.
  • Please don’t report issues with map data — they have nothing to do with Leaflet and will be declined. It uses OpenStreetMap on the website examples.
  • If you need to report a bug, please use GitHub issues instead.

Leaflet will become even better if you add …

You've used all your votes and won't be able to post a new idea, but you can still search and comment on existing ideas.

There are two ways to get more votes:

  • When an admin closes an idea you've voted on, you'll get your votes back from that idea.
  • You can remove your votes from an open idea you support.
  • To see ideas you have already voted on, select the "My feedback" filter and select "My open ideas".

  1. minor bug of projection

    leaflet is Great!!! I'm a GIS student and found leaflet very impressive indeed!

    OK. When I try to project a LatLng to SphericalMercator I observed a bug. You forgot to multiply the x,y with the Earth Radius. And I took R = 6378135 and it runs okay now. Thank you!

    • Popup details

      The date of the popup is reported sometimes wrong, perhaps lack of format description. So the popup properties of a pop-up from today (12 Nov 2012) is displayed (not always !!) as (11 Dec 2012).

      • Awesome product

        Hi. I have been looking for a product like this for a long time! Now that I have found it (thank you!) I have no idea how to start? I'm not a developer. It I do have java experience as I am the admin of an instance of Salesforce. I was wondering if you could point me in the right direction on how I start? I hVe no idea what to use to start. I want to use. County map of nj and populate different data sets by county so you can visually see the data. Again, thank you!!! Fred

        • virtual polyline thickness for mouseover

          If the polyline is very thin (1-3px), heavy to focus with the mouse over polylines. Also heavy to the touch. Comfortable thickness for projects is 6px and more, but not aesthetic appearance if very many lines .
          Is it possible to add a property for polylines (eg weight_mouseover, where weight_mouseover > = weight) virtual polyline thickness for mouseover?

          P.S. With the polygon and marker problems do not arise. Thank you.

            • Street names

              There are a few streets in Hawaii on the island of Kauai that need to be added to your map. Because same street changes name in some areas. Very important streets. Pee Road in Poipu and Nawiliwili Road in Lihue. My programmer, Iverve is creating Tracy's Map App for me with your Leaflet program. It looks great, however for tourists and users of the app these two streets need to be added. Can you please help with this? I can be reached at 808-652-6141. Mahalo Tracy Davidson.

                  • Descriptive & customizable tooltips for the different layers in the layer control.

                    Currently, I see no option to add the tooltip. This would be handy to explain the user, what each layer does.

                        • Leaflet.iconlabel in combination Mapbox?

                          I'm very new to javascript and leaflet software but I recently managed to build a customized leaflet map with the mapbox api. This worked fine. Now I tried to implement the leaflet.iconlabel plugin but it seems that the js library (libs/leaflet/leaflet-src.js) only works with OSM tiles. I have tried several combinations of js and css sources without success. Is there any chance to get the Leaflet.iconlabel plugin running with Mapbox? (actually it does somehow according to the the leaflet-routing-machine-project). Thanks!

                          • a fix to the functionality used in the "Layer Groups and Layers Control" tutorial

                            The map is practically impossible to use in the standard Android browser on my Galaxy SII under ICS as the layers icon/legend show and disappear abritrarily for moments only. Given the tag line is "...Mobile Friendly..." it's worth looking at

                              I'm preparing to launch a site built with 0.3.1, but since the 0.4 release, the API documentation page only shows the new API. I have a few remaining bugs to iron out, and would love to have the API reference to do it. It's far too late in our development cycle to upgrade to 0.4.

                                  • Correct mistakes in your GeoJSON Tutorial

                                    I am working on the tutorial that you have for GeoJSON. I noticed that the cordinates that you use in your example are reversed. For example, in your example of a simple GeoJSON feature the coordinates are described as [-104.99404, 39.75621]. I am still learning but I believe these are reversed.
