It is not recommended to have multiple select interactions in Openlayers. I can create a hover interaction using the select function with the pointMove condition to highlight features and display a popup if required. The interaction targets multiple layers and the styling is defined by the source of the feature. The problem which I am having is with overlapping features. In particular with lines and points from separate layers which intersect polygon features. If for example I run with cursor along a line into a polygon the line stays highlighted as expected. The same is true if I highlight a polygon but then want to highlight a point inside the polygon or a line which crosses the polygon. This seems to be impossible with the current library. The pointer condition is still true for the polygon geometry but I would like to assign an index to the other overlays with point or line features to highlight these features if the pointerMove condition validates.
