Expected Behavior

Actual Behavior

I was able to fix it by adding unique ID to every item and using it instead of title for item-value. (Playground)

I can also just drop item-value and it seems to work fine.

Are you sure VTreeView should work normally with incorrect declaration?

[yuwu9145]

item-value shouldn't be duplicated. You should either:

• "Adding unique ID to every item" like @J-Sek suggested above
• Or use return-object (demo)

I have managed to pinpoint specific place where the code get's stuck:

In theory we could mitigate issue by throwing exception once we detect duplicated ID. Tree view will be unexpectedly unable to expand specific node, but at least end-user's browser tab won't have a chance to freeze. I am curious about @yuwu9145 's opinion on it.

Adding a warning message would be a good solution, feel free to open a PR
