How can I add a blank selection at the bottom of my ng-options dropdown?

Question

How can I add a blank selection at the bottom of my ng-options dropdown?

At the moment, my setup looks something like this (in a simplified form):

<select ng-model=model.policyHolder ng-options="person.index as person.name for person in model.insurance.persons">
  <option value>Someone else
</select>

This code generates a dropdown menu featuring options with person names, and an empty one labeled "someone else" at the top. The real question here is how I can get that empty option at the end of the dropdown instead.

I want to stick with using ng-options if possible, given that adjusting the position of the default option seems like too minor a change to warrant switching to the slightly more verbose <option ng-repeat> method.

Appreciate any help on this matter!

Answer №1

When using options in a select element, remember to include the value="" attribute.

For example:

<select ng-model="model.policyHolder" ng-options="person.index as   person.name for person in model.insurance.persons">
  <option value="">Someone else</option>
</select>

If you want to ensure that "Someone else" appears at the bottom of the drop-down list when clicked, you can use the following code:

<select ng-model="model.policyHolder">
    <option ng-repeat="person in model.insurance.persons" value="{{person.index}}">{{person.name}}</option>
    <option value="">Someone else</option>
</select>

The answers provided by others appear to insert an element at the top rather than the bottom.

If you wish to include something at the end of the list, you can always do so in JavaScript.

For a functioning example, please refer to this plunk, modified from the angular select documentation.

Main section included below:

(function(angular) {
  'use strict';
angular.module('defaultValueSelect', [])
  .controller('ExampleController', ['$scope', function($scope) {
    $scope.data = {
     availableOptions: [
       {id: '1', name: 'Option A'},
       {id: '2', name: 'Option B'},
       {id: '3', name: 'Option C'}
     ],
     selectedOption: {id: '3', name: 'Option C'} //This sets the default value of the select in the ui
     };

     // Add another option as alternative
     // Might require $digest, depending on when this action is performed.
      $scope.data.availableOptions.push({ id: '', name: 'None of the above'})
 }]);
})(window.angular);
