@ilyankou, by any chance have you a way to add subtitles to layercontrol. Layer control groups plug in has a shortcoming that means my application of that plug in won't work (ismyrnow/leaflet-groupedlayercontrol#57 (comment)).

Any thoughts would be much appreciated!
Thanks.

@corrigancd Do you have a repo I can use as an example?

@ilyankou, it's line 227 and 233 in the file below. Im wondering how to add a subtitle to go before any poilayer is added? The addpoilayer method is called from viscontroller.js.

@corrigancd I would use jQuery to

1. Wait until a layer is either added or removed to the map, then:
   1. Iterate through children of layer-control div
   2. Insert subtitle before the relevant child

This is definitely not elegant but would work. Another approach would be to go to Leaflet source code and modify add/remove layer functions to also add the subtitle along with the checkbox + label.

@ilyankou,thanks for the tips. I may end up adding layer controlgroup min file to my repo and making the 1 line fix there.

Thanks for the super fast responses though 👍
