Request - use click instead of hover to open/close the control

[fisharebest]

At present, the control is opened/closed using mouseover/mouseout events.

This makes it difficult to operate by users with some disabilities and/or assistive technology.

Can you provide an option to open/close this control using mouse-click and/or keyboard?

This control tries to behave like "Control.Layers" control (https://leafletjs.com/reference-1.7.1.html#control-layers).
As far as I know, there is no such a feature in Leaflet.

However you can capture the events in the DOM, and call the expand() and collapse() methods (probably using also the option collapsed in the control creation)

Basically:

     var layerControlTree = L.control.layers(base, tree, {collapsed: false}).addTo(map);
     
     var collapsed = false
      $('.leaflet-control-layers').on('click', () => {
          if (collapsed)
            layerControlTree.expand();
          else
            layerControlTree.collapse();
          collapsed = !collapsed
      });
