Collapse list of markers under the map

Hi,
thanks a lot for your feedback (I`d appreciate your review at https://www.ads-software.com/support/view/plugin-reviews/leaflet-maps-marker even more ??
For a later pro version I also plan to add sorting/categories on frontend, though I cant tell you a release date for this feature yet, as I am currently working on the basis pro framework which should be available with v1.0 before summer. So please be patient ??
best,
Robert
