Assign multiple feature group in edit control in leaflet draw

How can i assign multiple the feature groups in edit control,

Assume we have two feature groups(It can be multiple),and we want to assign edit control to both groups.

This is groups,

var attLayerGroup = new L.FeatureGroup();
var photoLayerGroup = new L.FeatureGroup();

And this is, How i assign control to groups,

    var drawControl = map.addControl(new L.Control.Draw({
    edit: {
        featureGroup: photoLayerGroup,attLayerGroup,
        poly: {
            allowIntersection: true
        }
    },
    draw: {
        polygon: {
            allowIntersection: false,
            showArea: true
        }

    }
}));

Is it right way to assigning Edit control to FeatureGroup ? If not,How can we do it?
