Attempting to include a select element via transclusion

Looking to develop a custom directive named select that will replace a select element with a customized dropdown interface. For a clear example, check out this jsfiddle where the concept is demonstrated.

Let's consider the below select element:

<select ng-model="selectedOption">
    <option ng-repeat="option in options" ng-bind="option.value"></option>
</select>

The main objective of this select directive is to transclude the above code into the following template:

<section>
    <div ng-transclude></div>
    <ol> <!-- custom dropdown/select -->
        <li ng-repeat="option in options" ng-bind="option.value">
    </ol>
</section>

Below is how the directive should be implemented:

myApp.directive('select', function() {
    return {
        templateUrl: 'view/select.html',
        restrict: 'E',
        transclude: true,
        scope: {},
        link: function(scope, element, attrs) {}
    };
});

A few issues I'm encountering include:

  • The transclude seems to override the entire template (check jsfiddle)
  • Weird presence of option element
  • How can I access the bound data for creating the custom dropdown effectively?

Hoping to receive guidance on resolving these challenges!

Thanks!

UPDATE: Just to clarify, the reason behind transcluding the select element is for form functionality. For instance, if a user chooses an option from the custom dropdown, the directive should also select this option within the hidden native select element. This ensures synchronization with form features like $pristine status.

UPDATE2: Managed to somewhat accomplish what I need: jsfiddle. However, it requires renaming the directive and feels like a bit of a workaround with how the options array is obtained!

Answer №1

If you're looking for a cleaner way to access the options array post Update2, consider including it as a property within the directive scope.

directive:

scope: { name: '@', options: '=' },

html:

<selectx name="bar" ng-model="selectedOption" options='options'>

Check out this jsfiddle.


Alternatively, you have the option of creating the custom dropdown element within the link function, and then appending it to the existing select element:

myApp.directive('select', function($compile) {
    return {
        restrict: 'E',
        link: function(scope, element, attrs) {
            var custom = angular.element('<section>\
                      <ol>\
                        <li ng-repeat="option in options" ng-bind="option.value">\
                     </ol>\
                   </section>');
            custom.insertAfter(element);
            $compile(custom)(scope);
        }
    };
});

View it on this fiddle.

You can always adjust the position of the original select if insertAfter doesn't place it where you intend.
