How to add the Download button to a gpxGroup map

[marcoA152]

Hallo. I'm sorry to bother you but I struggling with this (my) issue: I'm trying to add a Download button to a multiple .gpx tracks map from your examples. On single gpx file map the button is shown but on multiple gpx map is not present. There is a way to add it?

Thanks in advance

Hi Marco,

probably when using the L.GpxGroup class the following variable is not setted:

this._downloadURL = url; // see: leaflet-elevation/src/control.js#741

Take a look at this other https://github.com/Raruto/leaflet-elevation/pull/160#issuecomment-1002209215 to start monkey patching that class as you wish (aka L.Class.include()).

Thank you i will try the way you have suggested, but but probably the fastest (and dirt) thing to do is to put a direct anchor to the gpx files under the "elevation-div"

Thanks for your work and for this amazing plugin!
