Hello, someone could help me, I am just starting my angular teachings and would like to know how I would create a directive for the list of categories and tasks. I have no idea what could be done if you can help me.

HTML:

<body>
    <div id="div-container" class="container ng-scope" ng-controller="TarefasController">
        <div class="row">
            <div class="col-xs-3 edit">

                <!-- Ínicio Adicionar Categoria -->
                <div class="page-header">
                    <h4>Adicionar Categoria</h4>
                </div>
                <div id="div-form">
                    <form role="form" class="ng-pristine ng-valid">
                        <div class="form-group">
                            <input type="text" class="form-control ng-pristine ng-valid" ng-model="categoria.nome" ng-model="name">
                        </div>
                        <button class="btn btn-info btn-block ng-pristine ng-valid" ng-click="addCategoria(categoria)" ng-model="infoIgual" ng-disabled="!categoria.nome" disabled="disabled">Adicionar</button>
                    </form>
                </div>
                <!-- Fim Adicionar Categoria -->

                <!-- Ínicio Adicionar Tarefa -->
                <div class="page-header">

                </div>

Do not allow onBackPressed to run Why does the background-image url look for the image inside the Content folder?

You can, before closing controller , put, for example:

.directive('ngSparkline', function() {
  return {
    restrict: 'A',
    template: '<div class="sparkline"></div>'
  }
});

Or declare the module within a variable and use the variable to create the directive.

var app = angular.module('TarefApp');

app.directive('ngSparkline', function() {
  return {
    restrict: 'A',
    template: '<div class="sparkline"></div>'
  }
});

In order to use HTML you only need to declare a div element, such as taking into account the value of the restrict attribute placed in directiva :

A: Only matches the attribute name
```
<div ng-sparkline></div>
```
E: Only matches element name
```
<my-sparkline></my-sparkline>
```
C: Only matches the class name
AEC: Combines with all of them
