Change cluster color when clicked

[FedericoChavazza]

• I'm reporting a bug, not asking for help
• I'm sure this is a Leaflet.MarkerCluster code issue, not an issue with my own code nor with the framework I'm using (Cordova, Ionic, Angular, React…)
• I've searched through the issues to make sure it's not yet reported

How to reproduce

I've been having some trouble lately trying to implement a className change when clicking a specific cluster (all I wanna do is to change the color of the cluster once is clicked). The reason why this happens is because the class itself does not persist, it changes on every cluster render. I tried to change the className manually by using the "clusterclick" event (did not work), and using the iconCreateFunction too (did not work either) because there is no way to see if that cluster was clicked or not. For some reason, zooming in or zooming out changes the leaflet_id too, so idk what to dooo :,(

• Leaflet version I'm using: ^1.8.0
• Leaflet.MarkerCluster version I'm using: ^1.5.3
• Browser (with version) I'm using: Google Chrome, using react too
• OS/Platform (with version) I'm using:

the change class idea

What behaviour I'm expecting and which behaviour I'm seeing

the cluster to change color once is clicked
