Hello,

In my T3 4.2.6, I created an extension. Suppose this extension has 2 sql 
tables (area and subarea).

AREA fields (except T3 fields) : name, comments
SUBAREA fields (except T3 fields) : name, subarea_uid

In my tca.php file I have :

$TCA["tx_myext_subarea"] =
...
"subarea_uid" => Array (		
			"exclude" => 1,		
			"label" => 
"LLL:EXT:myext/locallang_db.xml:tx_myext_reservation.subarea_uid",		
			"config" => Array (
				"type" => "select",	
				"foreign_table" => "tx_myext_area",	
				"foreign_table_where" => "ORDER BY tx_myext_area.uid",	
				"size" => 1,	
				"minitems" => 0,
				"maxitems" => 1,
			)
		),
...

That works very well. But now, I want to be able to select more than one 
area for one subarea. How can I do that ? And what does it mean at sql 
level (have to add fields, tables) ?

Thank you very much for your answer.
Greg
