is it possible to create a fully customized control ? #1156
Description
I would like to mimick in dash-leaflet the behaviour of the ipyleaflet binding of lealflet which allows me to integrate any DOM element into a control: https://ipyleaflet.readthedocs.io/en/latest/controls/widget_control.html. That's a very useful feature because then the wdget uyou place on the map is well aligned with all the other buttons and remain in the layout of the map even when resized.
As dash-leaflet is actually standing on your shoulders I would like to know if it's already possible to do it so I can start working on a PR on their repo.
