css - iterate over chunks of an array using ng-repeat

Question

My controller grabs people from the server:

$scope.people = [person1, person2, person3, person4, person5,...]

My template needs to display three people per line. For example if it was a table:

<table>
    <tr>
        <td>person1</td><td>person2</td><td>person3</td>
    </tr>
    <tr>
        <td>person4</td><td>person5</td><td>person6</td>
    </tr>
</table>

I wasn't sure how to conditionally apply the <tr> when $index % 3 == 0 or what the best practices are. I know how to do this by adding grouping logic to the controller but I thought it would be best to keep design logic out of the controller.

There isn't an existing way to do what you are saying with a table. The easiest way to do what you want is to use divs with fixed widths, so that they will auto-wrap after three.

Here is an example:

HTML

<div ng-app="app">
    <div ng-controller="TableCtrl" class="my-table">
        <span ng-repeat="person in people" class="person">{{person}}</span>
    </div>
</div>

CSS

.my-table{
    width: 400px;
    height: 400px;
    border: 1px solid black;
}

.person{
    width: 100px;
    display: inline-block;
    white-space: nowrap;
    border: 1px solid black;
}

JavaScript

var app = angular.module('app',[]);
app.controller('TableCtrl', function($scope){

    $scope.people = ['Aaron', 'Abraham', 'Adam', 'Aristotel', 'Aziel', 'Azod', 'Azood'];

});
