ng-options自定义排序角度选择菜单，用于特定值

Question

<select name="region" id="region" ng-options="id as name for (id, name) in regions[entry.country]" ng-model="entry.region"  class="form-control select-styled" required></select>

I wanna use some kind of filter or custom sort to sort regions if entry.region is equal to Japnese. Currently options are displayed by key, and i wanna sort them by value (japanese alphabet) ? Any idea how to start?

You can create a custom filter to check what's the region and then apply sorting.
