Extended Settings

cms_system allows site administrators and/or developers to add extended settings to their site by editing the extended_settings_fields in a config file.
The file is located at /application/config/extended_settings.php.

When the site finds settings in this file, it will add a fourth tab to the Site Settings page, titled Extended Settings (the title can be modified in the settings_lang language file under set_tab_extended).
The file allows configuration of the settings included on this tab as well as permissions required to view them, the valid values, and the controls used to render them.
When saving the site settings, the extended settings are saved as well in the same location, and the extended settings can be accessed the same way the other settings are accessed.
If the extended_settings_fields config array is empty, the tab will not be displayed on the Site Settings page.

Defining the Fields

Example:

The configuration below will add 5 fields to the Extended Settings tab, 3 of which have permission requirements.
Each field is defined in its own array within the extended_settings_fields array.

$config['extended_settings_fields'] = array(
    array(
        'name'  => 'extended_settings_test',
        'label' => 'Test Label',
        'rules' => 'trim',
        'form_detail'   => array(
            'type'  => 'dropdown',
            'settings'  => array(
                'name'  => 'extended_settings_test',
                'id'    => 'extended_settings_test',
