The autoCheckNodes option allows the sub-nodes to be checked when the parent nodes are checked. To use this option, showCheckboxes must be set to "true."
$(function () {
// Get value
var returnsValue; // Type: boolean
returnsValue = $(".selector").wijtree("option", "autoCheckNodes");
// Set value
var newValue; // Type: boolean
$(".selector").wijtree("option", "autoCheckNodes", newValue);
});
