Display chosen preferences in an Angularjs dropdown alongside additional options

I'm currently developing a blogging software and have implemented an AngularJS dropdown for selecting post terms. Here's the code:

   <select multiple="multiple" name="terms" ng-model="post.data.attributes.term_ids" required>
             <option value="" disabled="" selected="">Tags</option>

             <option ng-repeat="term in terms | filter: { taxonomy: 'tag' } " value="{{term.id}}">{{term.name}}</option>
     </select>

While this works when creating posts, I'm facing an issue when trying to edit posts. I want to display the terms that were previously selected during post creation.

In other words, if the term's ID matches any in `post.data.attributes.term_ids`, then it should be pre-selected in the dropdown. I've gone through the documentation and examples but still haven't figured out how to achieve this. Any help would be greatly appreciated.

Answer №1

One simple solution is to utilize the ngSelected attribute:

<select multiple="multiple" name="terms" ng-model="post.data.attributes.term_ids" required>
             <option value="" disabled="" selected="">Tags</option>

             <option ng-repeat="term in terms | filter: { taxonomy: 'tag' } " value="{{term.id}}" ng-selected="post.data.attributes.term_ids.indexOf(term.id) > -1">{{term.name}}</option>
     </select>

Alternatively, you could consider using ngOptions. Here's an example:

<select multiple="multiple" name="terms" ng-model="post.data.attributes.term_ids" required ng-options="term.name for term.id in terms | filter: { taxonomy: 'tag' } ">
</select>
