Dynamically setting Core Multiple flag

[ngrkishore]

How can I set multiple flag to different value programmatically. We have a scenario where the user can only select one checkbox or multiple selections based on a condition. How can I do this.

$("[data-tree]").jstree({
core: { animation: 0, multiple:false/true, themes: { icons: false } },
search: {
close_opened_onclear: false,
show_only_matches: true,
show_only_matches_children: true,
},
plugins: ["wholerow", "checkbox", "search"]
});
