I have an application showing cadastral parcels. When a parcel is clicked, the applications makes zoom to the extent of this feature and prepares a floating pane where it is possible to load some layers specific to that parcel.
The problem is that I think that when the studied feature is clicked, there are lots of lines, points and polygons around that feature, so it is a bit difficult to concentrate in the feature that user is studying.
So I would like to know how can I add a shade or a grey overlay to everything that is NOT the selected feature, so the user has highlighted only what has selected. Then, clicking on a close button or similar, shade has to go out. Yes, it is a pure aesthetic question, but I would like to give to my application a serious and professional look. :-)
Please, consider that at this point, there could be up to 5 or 6 different layers loaded in the map.
Does anyone know how to do this process? I am not sure if it is possible to hide everything except one feature of one of the loaded layers.
Thanks to everyone!
PD - Just to provide an example. Check the first item of the "What I would like to do" section in this question.
