[OpenLayers-Users] select multiple features with a click

[Jim White]

I have a vector layer of points with images. I want to click on the map 
and select one or more features if several points are close together.

   var select_control = new OpenLayers.Control.SelectFeature(vector_layer,
             {"onSelect": test,
                "multiple": true});

This doesn't seem to work. It selects one feature, but not two if two 
points are close together. How to do this?
