How can I split ng-repeat data into three columns using AngularJS and Bootstrap?

Splitting ng-repeat Data into Three Columns

AngularJS allows developers to display dynamic data in a web page using the ng-repeat directive. However, when working with a large number of data elements, it often becomes necessary to organize the elements in a structured layout. This requires the splitting of data into columns, which can be achieved using various approaches.

Incorporating Bootstrap for Alignment

Bootstrap, a popular front-end framework, provides a simple mechanism to create responsive and consistent grid layouts. By incorporating Bootstrap into our code, we can effortlessly align text boxes or other form elements into three equal and neatly arranged columns.

Step 1: Controller Transformation

The most efficient and reliable method to divide data into columns is to manipulate it within the controller. This involves creating a chunk function and using it within the ng-repeat directive:

<code class="javascript">function chunk(arr, size) {
  var newArr = [];
  for (var i = 0; i < arr.length; i += size) {
    newArr.push(arr.slice(i, i + size));
  }
  return newArr;
}

$scope.chunkedData = chunk(myData, 3);

replace the ng-repeat with a new code segment:

<code class="html"><div ng-repeat="rows in chunkedData">
  <div class="col-4" ng-repeat="item in rows">
    {{item}}
  </div>
</div></code>

This method ensures that the data remains in its original format and can be manipulated or submitted without any alterations.

Step 2: View-Based Chunking

While it is possible to perform data splitting using filters within the view, it is crucial to note that this approach is only suitable for display purposes. Any form elements added within such filtered views can lead to potential issues. It is recommended to manipulate data in the controller for any interactive elements. However, if you still wish to use view-based chunking, you may consider utilizing a library like lodash to enhance its stability and performance.
