Hi everybody,

I found this link http://christian.fei.ninja/Angular-Filter-already-selected-items-from-ng-options/

I've defined the following so far:

<div class="col-md-4">
                <select class="form-control" ng-model="newLink.groupNo"
                        name="groupNo" id="groupNo" 
                        ng-options="t.value as t.text for t in metaData.spGroups"></select>
            </div>

I need to only allow to select groups which are not already in the $scope.currentSChannels.scgsLink.groupNo column.

I originally tried

| filter:{ value : !currentSChannels.scsgLink.groupNo }

but then my drop down came empty.

I see in the blog by that author that he implements custom excludeFrom filter and passes an array of things. But how exactly that works? Does it check each value from all columns in the first array against values in all columns of the second array? How can I change the above to make sure that only value (or newLink.groupNo) is checked against groupNo column and not all other columns of the array are checked?

Thanks in advance.
