Dropdown: unselects option when loses focus

Hmm the hook form example on the showcase is working? https://primereact.org/dropdown/#hookform

Also I just disabled Strict Mode and it looks like its working: https://stackblitz.com/edit/vitejs-vite-8uvnxd?file=src%2Fmain.tsx

So its a strict mode issue i think.

In your link, for me, it is still happening. You need to test it twice. The first selection works fine.

Yep you are right now it works the first time but not subsequent times.

Here I added console.log to the events: https://stackblitz.com/edit/vitejs-vite-8v5uqj?file=src%2FApp.tsx

The problem is the onKeyDown event.

Yep
