Troubleshooting problems with integrating Jquery Plugin in Angular for creating dynamic dropdown menus

Currently, I am utilizing the selectric jQuery plugin in conjunction with my Angular dropdown.

When I have the dropdown options hardcoded in the HTML, everything functions correctly with just the following code:

$('select, .select').selectric();

However, if I dynamically load my dropdown data like this:

<select class="form-control" ng-model="myAddress" ng-options="address.addressLines for address in search.result.addresses" size="{{numAddressOptions}}">
</select> 

An error is triggered in the selectric plugin:

TypeError: $li[index] is undefined

I attempted to incorporate the selectric plugin as a directive in the following way:

<select class="form-control" ng-model="myAddress" ng-options="address.addressLines for address in search.result.addresses" size="{{numAddressOptions}}" selectric>
        </select>

Additionally, here is my directive:

.directive('selectric', function(){
  'use strict';
  return{
    restrict: 'AE',
    link: function(scope, element, attrs) {
      $(element).selectric();
    }
  };
});

Does anyone have any insights on what may be causing the issue here?

Due to the priority of ng-options being 0, there is no guarantee that your directive's link function will execute afterwards: Angular 1.3.7 Compile Docs.

Understanding Priority:

In cases where multiple directives are applied to a single DOM element, specifying the order in which they should be executed becomes necessary. The priority attribute helps in sorting the directives based on their numerical value before they are compiled. Directives with higher priority values are compiled first. Pre-link functions follow the same priority order while post-link functions run in reverse. However, when directives have the same priority, the execution order remains undefined. By default, the priority is set at 0.

To ensure the desired functionality, it is recommended to pass objects into a directive that generates the select element within its template. A helpful example can be found here: . This approach will properly sequence the invocation of your link method after the compile phase for directives within your template has been completed.

In addition, update restrict: 'AE', to restrict: 'E', and adjust your HTML structure as follows:

<selectric addresses="{{ search.result.addresses }}" ...></selectric>
