Great and it works locally with my markers and popups BUT I am using it on wix and I don't know how to set it up so it can access the markercluster stuff

[@eduardmart1237]

How do I make them load from the backend only when zoomed in? For instance if I have tens of thousands of markers?

[@gissolutions4604]

Thanks so much for the question. Honestly I'm not sure how to go about doing that. If you come across a solution, please let me know.

​@@gissolutions4604 Could you create a demo video of leaflet pulling data from geoserver? and also be interested to create widgets on leaflet like dynamic filters, slider and charts :D

[@gissolutions4604]

@@cmlosaria Thanks so much for the suggestions, I'll add them to my list of upcoming videos!

How do you deal with the map lagging issue when many markers are added. I click on the clusters and they don't expand.

[@gissolutions4604]

I have a little lag time on my end, but not that bad. Not entirely sure how to enhance the performance.

[@brians4265]

I get an error saying that L is not defined and that markerClusterGroup is not a function. I have followed all the steps in the video . What can I do ? Thank you

[@gissolutions4604]

Thanks for the feedback...make sure that the markercluster src code is BELOW the leaflet.js src code. Give that a try and let me know if that works?

[@majaturkalj4773]

I am trying to add popups to the markers, but whenever I try to do this, I lost the clustering on the map. Is there any hint how to add this? Thanks.

[@gissolutions4604]

Great question and thanks for reaching out. I haven't tried adding popups to the markers while enabling the clustering. Would have to dig further in to see if it's possible. Please let me know if you find a solution in the meantime!

why it is the design is not implementing in my map

[@gissolutions4604]

Hard to say without providing additional information.
