- minitems (type => file)¶
integer > 0
This property can also be overridden by page TSconfig.
Example, exactly one image has to be attached:
// After 'columns' => [ 'image' => [ 'label' => 'My one and only image', 'config' => [ 'type' => 'file', 'minitems' => 1, 'maxitems' => 1, 'allowed' => 'common-image-types' ], ], ],
