Hi guys

I'm currently working on a property editor where I would like to setup some filtering like we know it from the Multinode treepicker (MNTP).

I'm using the entityResource and passing a query to it, which works just fine. However I would like to improve it so that I'm only allowed to select content nodes, which have a specific alias - Just like when we setup allowed types on the MNTP.

I have tried looking in the Umbraco source code but can't seem to find any clues - I'm not sure that this is currently even possible?

My current code looks like below

$scope.pickContent = function(idx){
    var config = {
        multiPicker: false,
        entityType: "Document",
        type: "content",
        treeAlias: "content",
        query: $scope.model.config.nodetype,
        currentId: $routeParams.id
    };

    entityResource.getByQuery(config.query, config.currentId, config.entityType).then(function(entity){

        dialogService.contentPicker({
            section: config.type,
            treeAlias: config.type,
            multiPicker: config.multiPicker,
            startNodeId: entity.id,
            callback: function(data){

                  //Updating some scope variables

            }
        });

    });

}

As I mentioned it works but I would like to tweak it so I'm only allowed to pick certain document types (If possible).

Looking forward to hear any tips/suggestions :)

Cheers, Jan
