Here is the code snippet:
<select ng-model="group" ng-options="g.key for g in groups"></select>
Even though $scope.groups consists of a map like this: {'a':'', 'b':'', 'c':''}
I want the select to display the keys of the map: a, b, c
Currently, it doesn't select anything.
How can I modify the ng-options?
UPDATE 1
g for g in Object.keys(groups) also does not work.
If you want to incorporate a dropdown menu with Angular, this is the syntax you should use:
<select ng-model="group" ng-options="key for (key, g) in groups"></select>
To learn more about the select directive and its ngOptions feature, make sure to explore the comprehensive documentation provided here: http://docs.angularjs.org/api/ng.directive:select
