Admin side functionality:

• option_type($type) - get instance of a registered option type.

  $option_type_text = fw()->backend->option_type('text');
  
  echo $option_type_text->render('demo', array( 'value' => 'Demo Value' ));

      'demo',
      array(
          'type'  => 'text',
          'label' => __('Demo Label', 'fw'),
          'desc'  => __('Demo Description', 'fw'),
          'html'  => __('Demo Help Tip', 'fw'),
          'value' => 'default value',
      ),
      array(
          'id_prefix'   => 'custom-id-prefix-',
          'name_prefix' => 'custom_name_prefix',
          'value'       => 'overwrite default value'
      ),
      'taxonomy'
  );
  

• render_options(&$options, &$values = array(), $options_data = array(), $design = 'default') - generate html from any array of options.

  $options = array(
      'option-1' => array( 'type' => 'text',     'value' => 'default value 1' ),
      'option-2' => array( 'type' => 'textarea', 'value' => 'default value 2' ),
  );
  
  // simple usage
  echo fw()->backend->render_options($options);
  
  $values = array(
      'option-1' => 'Some value', // this overwrites default value
      // 'option-2' value is not specified, so it will have default value
  );
  
  // advanced usage
  echo fw()->backend->render_options(
      $options,
      $values,
      array(
          'id_prefix'   => 'custom-id-prefix-',
          'name_prefix' => 'custom_name_prefix',
