Hi,

I'm Matteo a gis developer,
after a while searching on your documentation / github / stackoverflow i 
come to you :)
I have a list of questions for you.

I have a Feature like this: 
{
    type: "GeometryCollection",
    geometry: {
        geometries: [
            {
                type: "MultiPolygon",      <----   i want this or
                coordinates: [ polygon1, polygon2 ]  <------ i want 
polygon1 if user has clicked on it
            }, {
                type: "MultiLineString",
                coordinates: [...]
            }, {
                type: "MultiPoint",
                coordinates: [...]
            },
        ]
    }
}

is there a way to retrieve the geometry selected by the user instead of the 
whole feature the ol.interaction.Select returns?

if yes, in case of MultiGeometries is there a way to get the internal 
polygon/line/point selected? (if not I can try to avoid the use of 
multigeom)

probably this can lead to another problem, what if the point clicked by the 
user is inside the intersection of two or more geometries, i.e. 2 polygons, 
1 polygon and 1 line? (in that case i could chose the geom based on the 
z-index)


if you need more details, please ask.

Cheers.
