if i print_r $materials i can see the info in an array but i dont know how to enter it in < select >

$db = JFactory::getDBO();
							$sql = "SELECT material_id AS val, title, sub_note "
								 . " FROM #__rsform_material ";

									$db->setQuery($sql);
									$materials = $db->loadObjectList();
									$matlist[]		= JHTML::_('select.option',  '0', JText::_( 'Fabric Subcategory' ), 'val', 'title');
									$matlist			= array_merge( $matlist, $materials );
									echo JHTML::_('select.genericlist',   $matlist, 'material', 'class="inputbox" size="1"','val', 'title',  $row['material_id'] );
