Angularjs Sorting data in ng-repeat two items

I have two jsons: templates, and images

$scope.templates = [
        {"id_template": 1, "name": "First Template", "group": "sport"}
        {"id_template": 2, "name": "Second Template", "group": "animals"},
        ];

    $scope.images = [
        {"id_image": 1, "id_template": 1, "title":"Image Lewy"},
        {"id_image": 2, "id_template": 1, "title":"Image ball"},
        {"id_image": 3, "id_template": 2, "title":"Image dog"},
    ]

I would like to display in the view images sorted by id_template. I know that you must create a loop in the loop but do not know how ? My view.html: 

<div class="images" ng-repeat="template in templates">
 {{template: name}}
 Images to this template: 
 <ul>
  <li ng-repeat="image in images | filter:template.id_template">{{image.title}}</li>
</ul>
</div>

You can sort in angular by using orderBy filter. Please go through https://docs.angularjs.org/api/ng/filter/orderBy documentation if you want more details. From example below the result will be ascending and if you want it to be descending order add '-template_id'

Ascending

<div class="images" ng-repeat="template in templates | orderBy: 'template_id'">
 {{template.name}}
 Images to this template: 
 <ul>
  <li ng-repeat="image in images | filter:{id_template:template.id_template}">{{image.title}}</li>
</ul>
</div>

Descending

<div class="images" ng-repeat="template in templates | orderBy: '-template_id'">
 {{template.name}}
 Images to this template: 
 <ul>
  <li ng-repeat="image in images | filter:{id_template:template.id_template}">{{image.title}}</li>
</ul>
</div>

your almost there but have a small syntax error which is you need to print like {{template.name}} instead of {{template: name}}

<!DOCTYPE html>
<html ng-app="plunker">

  <head>
    <meta charset="utf-8" />
    <title>AngularJS Plunker</title>
    <script>document.write('<base href="' + document.location + '" />');</script>
    <link rel="stylesheet" href="style.css" />
    <script data-require="[email protected]" src="https://code.angularjs.org/1.4.12/angular.js" data-semver="1.4.9"></script>
    <script src="script.js"></script>
  </head>

  <body ng-controller="MainCtrl">
    <div class="images" ng-repeat="template in templates">
 {{template.name}}
 Images to this template: 
 <ul>
  <li ng-repeat="image in images | filter:{id_template:template.id_template}">{{image.title}}</li>
</ul>
</div
  </body>
<script>
  var app = angular.module('plunker', []);

app.controller('MainCtrl', function($scope) {
  $scope.templates = [
        {"id_template": 1, "name": "First Template", "group": "sport"},
        {"id_template": 2, "name": "Second Template", "group": "animals"}
        ];

    $scope.images = [
        {"id_image": 1, "id_template": 1, "title":"Image Lewy"},
        {"id_image": 2, "id_template": 1, "title":"Image ball"},
        {"id_image": 3, "id_template": 2, "title":"Image dog"},
    ]
  
 
});
</script>
</html>

you must use OrderBy for sorting items in angularjs

<li ng-repeat="image in images | orderBy:template.id_template">{{image.title}}</li>
