I am working as volunteer on a simple map for an NGO, I have some point layers with rule-based symbology. When I load these layers in qgis2web the symbology disappears, both in Leaflet and OpenLayers. I think I have the same problem posted by Sophia R. and solved (Can qgis2web display rule-based layer style?).
The matter is that I'm new in QGIS and I don't know how to "preselect your layer with "X" = 'a' and export this selection as a new layer" as suggested by Riccardo.
How can I do this?
