There's an example in the Leaflet-ESRI documentation here: https://esri.github.io/esri-leaflet/examples/finding-features.html But the code doesn't seem to actually work, neither on the example page nor when I cut and paste it into jsbin.
I'm trying to create a search/find box for a user to provide text and then find features that include that text in their attributes. I'd love to see examples of this Find task in working action.
EDITED TO ADD: When I load the above page as http:// instead of https://, that does allow the features to be added to the map. However, the Find box still appears not to function properly. I'd like to see an example of the Find tool working properly.
