[OpenLayers-Users] drillDown: multiple requests but only first in pop-up

[Bart van den Eijnden]

Please see the api docs, this does not work with HTML, you need something like GML as the output format for GetFeatureInfo.

    /**
     * APIProperty: drillDown
     * {Boolean} Drill down over all WMS layers in the map. When
     *     using drillDown mode, hover is not possible, and an infoFormat that
     *     returns parseable features is required. Default is false.
     */

Best regards,
Bart
