I'm trying to create a custom filter that strips HTML on my select menu. This is what I've tried, but it doesn't work.

            <select
                ng-options="item.name for item in list | htmlToPlaintext">
                <option value="">Select</option>
            </select>

It's rendering empty values.

            app.filter('htmlToPlaintext',
            function () {
                 return function (items) {
                      var filtered = [];
                      angular.forEach(items, function (item) {
                            var stripped = String(item).replace(/<[^>]+>/gm, '');
                            filtered.push(stripped);
                      });
                      return filtered;        
                 }
            });

Has anyone applied this type of filter to ng-options in Angular?

Your need to modify your filter like shown below and your html snippet too. You can apply the filter not whole items but each title.

Below is the demo:

angular.module('selectFilters', ['filters']);
angular.module('filters', []).filter('htmlToPlaintext', function() {
    return function(text) {
      return String(text).replace(/<[^>]+>/gm, '');
    }
  });

function ItemCtrl($scope, $filter){
    $scope.Items = [
        {ID: '000001', Title: '<b>Chicago</b>'},
        {ID: '000002', Title: '<b><i>New York</i></b>'},
        {ID: '000003', Title: '<div><p>Washington</p></div>'}
    ];    
}

<script src="https://ajax.googleapis./ajax/libs/angularjs/1.2.23/angular.min.js"></script>
<div ng-app="selectFilters">
    <div ng-controller="ItemCtrl">
        <div>
            <select ng-model="item" ng-options="(item.Title | htmlToPlaintext) for item in Items"></select>
        </div>
    </div>
</div>
