How to use collection suite for selection?

Hi,

    I have created a collection of items I need to select. So what I need to do for selecting the collection which I created?

Code :

AEGP_Collection2H        collectionH        = NULL;
AEGP_CollectionItemV2    collectionItem;
AEGP_StreamRefH            streamH;

ERR(suites.DynamicStreamSuite4()->AEGP_GetNewStreamRefForLayer(S_Plugin_ID, layerH, &streamH));
collectionItem.type                   = AEGP_CollectionItemType_LAYER;
collectionItem.u.layer.layerH    = layerH;
collectionItem.stream_refH      = streamH;

ERR(suites.CollectionSuite2()->AEGP_NewCollection(S_Plugin_ID, &collectionH));
ERR(suites.CollectionSuite2()->AEGP_CollectionPushBack(collectionH, &collectionItem));

Any suggestions?

Thanks,
