Hello Sam,

Thank you for reaching out to us.

The provided example seems like the one from the Kendo UI for Vue official documentation: https://www.telerik.com/kendo-vue-ui/components/dropdowns/dropdowntree/custom-rendering/#toc-items-and-value-element. The demo works as expected there. However, I tested opening it in both CodeSandbox and Stackblitz and reproduced the issue there. I can confirm that is a bug and log it in our public issue tracker repository where we log and plan for fixing bugs:

https://github.com/telerik/kendo-vue/issues/659

Thank you for bringing this to our attention! As a token of gratitude, I have updated your Telerik Points.

As a workaround, I can suggest downgrading the @progress/kendo-vue-dropdowns package to v3.14.2, where it works as expected.

I hope that will help. We will do our best to provide a fix as soon as possible.

Regards,
Silviya
