Infragistics Drag and Drop Tree Expand Multiple Nodes Simultaneously

Question

I am using the following Infragistics component for viewing hierarchical data. http://www.igniteui.com/tree/drag-and-drop-single-tree

I could able to load data correct but the problem is wI cant expand multiple nodes simultaneously. I mean when I expand a node the other node collapsed expanding only the current node. Can some one please suggest if there is any configuration setting I am missing to accomplish this?

I want the nodes once expanded will remain expanded until user collapses it again.

Thanks, Krishna Prasad

Answer 1

The option that controls that is singleBranchExpand. Set it to false to allow multiple nodes to be expanded at the same time. http://jsfiddle.net/ywtLL7ka/

$("#tree").igTree({
    singleBranchExpand: false,
});
