laravel delete method not working

I've made a small laravel project but the delete method is nog working:

I use a resource controller my route is :

Route::resource('roles','Admin\RoleController');

in my view I have

 <form action="" style="display:inline">
    @method('delete')
    @csrf
    <button type="submit" class="btn btn-danger"><i class="fa fa-trash"></i></button>
 </form>

But when i click the button it will show me the role ( = get method of the resource ) What am I doing wrong ?
