Hello

It's definitely possible to display items in an ng-repeat in alphabetical order while still being able to track them by their original index for CRUD operations. You can achieve this by using a combination of AngularJS features. Here's a basic outline of how to do it:
Sort the Data Array: First, you should sort your array of Block Groups by their titles before rendering it in ng-repeat. This ensures that they are displayed in alphabetical order. You can do this in your controller or as a filter.
$scope.sortedBlockGroups = $filter('orderBy')($scope.blockGroups, 'title');
Display Sorted Data in ng-repeat: In your HTML, use the sorted array in ng-repeat.
Track by Original Index: To handle CRUD operations, you can continue to track by the original index. You can achieve this by maintaining a mapping of the original index to the sorted index. This allows you to keep track of the correct Block Group when performing CRUD operations.
// Create a mapping from original index to sorted index
$scope.indexMapping = {};
angular.forEach($scope.blockGroups, function (blockGroup, originalIndex) {
$scope.indexMapping[originalIndex] = $scope.sortedBlockGroups.indexOf(blockGroup);
});
// Use the mapping for CRUD operations
$scope.deleteBlockGroup = function (originalIndex) {
var sortedIndex = $scope.indexMapping[originalIndex];
$scope.sortedBlockGroups.splice(sortedIndex, 1);
// Perform the delete operation on the original data array as well.
$scope.blockGroups.splice(originalIndex, 1);
};
With this approach, you maintain a sorted display while still having the ability to perform CRUD operations based on the original index of the Block Groups. The indexMapping object keeps track of the relationship between the original and sorted indices, allowing you to perform operations on the original data array correctly.
I wish that helps.
