[ljharb]

indeed , the IconLeft and IconRight functions are components - they take props, and render jsx, and are named in PascalCase. You could try IconLeft() { return <ChevronLeft className="h-4 w-4" />; } etc?

@ljharb tried this but still getting the error

[ljharb]

then i don't think there's a way to avoid it here; these are components, so you can either define them in another file or ignore the warning, as you've done.

Okay @ljharb , Thanks for Help
