				'text' => $txt['foo'], // required
				'class' => 'foo', // optional
			),
			'input' => array(

				'attributes' => array(

					'value' => $foo,

				),
			),

				),

						'value' => '1',
						'selected' => true,
					),

						'label' => $txt['option_2'],
						'value' => '2',
						'selected' => false,
					),

						'options' => array(
							'option_3' => array(
								'label' => $txt['option_3'],
								'value' => '3',
								'selected' => false,
							),
							'option_4' => array(
								'label' => $txt['option_4'],
								'value' => '4',
								'selected' => false,
							),
						),
					),
				),
			),
		);

		$context['posting_fields']['baz'] = array(
			'label' => array(
				'text' => $txt['baz'], // required
				'class' => 'baz', // optional
			),
			'input' => array(
				'type' => 'radio_select', // required
				'attributes' => array(
					'name' => 'baz', // optional, defaults to posting field's key
				),
				'options' => array(
					'option_1' => array(

					),
					'option_2' => array(
						'label' => $txt['option_2'],
						'value' => '2',
						'selected' => false,
					),
				),
			),
		);

		The label and input elements are required. The label text and input
		type are also required. Other elements may be required or optional
		depending on the situation.

		The input type can be one of the following:

		- text, password, color, date, datetime-local, email, month, number,
		  range, tel, time, url, or week
		- textarea
		- checkbox
		- select
		- radio_select

		When the input type is text (etc.), textarea, or checkbox, the
		'attributes' element is used to specify the initial value and any
		other HTML attributes that might be necessary for the input field.

		When the input type is select or radio_select, the options element
		is required in order to list the options that the user can select.
		For the select type, these will be used to generate a typical select
		menu. For the radio_select type, they will be used to make a div with
		some radio buttons in it.

		Each option in the options array is itself an array of attributes. If
		an option contains a sub-array of more options, then it will be
		turned into an optgroup in the generated select menu. Note that the
		radio_select type only supports simple options, not grouped ones.

		Both the label and the input can have a 'before' and/or 'after'
		element. If used, these define literal HTML strings to be inserted
		before or after the rest of the content of the label or input.

		Finally, it is possible to define an 'html' element for the label
		and/or the input. If used, this will override the HTML that would
		normally be generated in the template file using the other
		information in the array. This should be avoided if at all possible.
