Disable Parent Selection

[William]

Is there a way to disable parent selection?  I only want the user to be able to select one child node.

[William]

I may have figured out one way to do this.  I added the select event and then added this script to the razor view.

        function onDropDownSelect(e) {
            var dataitem = e.sender.dataItem(e.node);
            console.log(dataitem);
            if (dataitem.hasChildren) {
                e.preventDefault();
            }
        }

Two questions:

1) Is this the best way to do this?

2) I initially tried to include this function in a javascript file that I include in the view but it could not find the function.  Is there a way to put this in a js file and include the js file as I like to keep my razor clean?

Here are the answers to your questions:

1. Question 1: Yes, the approach you are using is the proper way of preventing selection of parent nodes.
2. Question 2: Please check this Static files in ASP.NET Core article for detailed instructions about all the needed configurations you must set to include your JavaScript file.
