How do i check if the node is expanded

[Svetlin]

I want to collapse the node on single click. To do that i need to know if the node is expanded so i can call collapse(e.node)

Thanks a lot team

Hello Svetlin,


You could get this information from the data-expanded attribute of the nodes.
E.g.

var isExpanded = $(node).attr("data-expanded");

if (typeof isExpanded !== 'undefined' && isExpanded !== false) {
    // ...
}

I wish you a great day!
