// You must init the multiple select with $('#my-select').multiSelect() before calling one of the following methods

$('#countries').multiSelect('select', 'value');   // Select the item with the value given in parameter
$('#countries').multiSelect('deselect', 'value'); // Deselect the item with the value given in parameter
$('#countries').multiSelect('select_all', true);  // Select all elements. If parameter visible set to true, it will select only visible items. Otherwise it will also select hidden items.
$('#countries').multiSelect('deselect_all');      // Deselect all items previously selected
