AngularJS - remove select option from options collection on select...

[regdunlop0]

I have 3 selects that use the same options json collection I pull from storage.  I am trying to remove/disable option items from the subsequent selects once they have been selected.

Example:

Select 1

Options(fruit collection)

 Apple X

 Orange

 Banana

Select 2 (fruit collection - with Apple removed/disable due to selected)

 Orange

 Banana

How can I do this.  Seems a pretty regular need.

Thanks!

Hello~

I cannot tell you in detail.

But you can use two way.

One is scope.$watch, another is ng-change built-in directive.

You maybe have to consider with $index.

Good luck to you!

Thanks Ginie,

I see I can add ng-change to trigger a directive.  

<select class="form-control" ng-model="newReport.features1" ng-change="setSelected()" ng-options="feature.feature_name as feature.feature_name for feature in features | filter:{selected:false}" required>

My question is - how do I write the directive to set selected on the ng-option (not the ng-model) to true?

Thanks.
