I have two user defined elements:

hook_elements() {
	...
	$type['grid'] = array (
		'#tree' => TRUE,
	);
	
	$type['listbox'] = array(
		'#input' => TRUE,
		'#tree' => TRUE,
	);
	...
	return $type
}

so far so good but when I want to use the types like the next example:

	$form['test_grid'] = array(
		'#name' => 'test_grid',
		'#type' => 'grid',
		'#title' => t('Grid test'),		
	);
	
	$form['test_grid']['lb1'] = array(
		'#name' => 'lb1',
		'#type' => 'listbox',
		'#options' => array('optie 1', 'optie 2', 'optie 3'),
	);

the second type (listbox) does not show up. It shows up when I remove test_grid from the type. But I want to use variant in the example. Can anybody tell me how to use 'nested' elements?

Here is an example of grouped elements (sort of nested) using the fieldset element

		$form['range'] = array('#type' => 'fieldset',
		 							'#title' => t('Range check'),
		  							'#collapsible' => TRUE,
		  							'#collapsed' => FALSE,
		  							'#description' => t('Only applies if value is numeric.  If set, used to check that user input is in the range specified.'));
		  											
		$form['range']['min_value'] = array('#type' => 'textfield', '#title' => t('Lower Value'),
	    '#size' => 32, '#maxlength' => 64,
	    '#description' => t('If set, valued entered as part of action must be greater than or equal to this value.'),
	    '#default_value' => $input->min_value);	
	
		$form['range']['max_value'] = array('#type' => 'textfield', '#title' => t('Upper Value'),
	    '#size' => 32, '#maxlength' => 64,
	    '#description' => t('If set, valued entered as part of action must be less than or equal to this value.'),
	    '#default_value' => $input->max_value)

Thanx, but that's not what I want. That works for the default elements fieldset, but I want that it works with my defined elements. So, if I want to use the group structure $form['a']['b'] with my own types grid and listbox (see first post) it doesn't work, but when I don't use a group like $form['a'] it works. There must be a reason why it doesn't work with my defined elements.

Hopefully someone can give some advise or an example how has to be.
