How to validate on initial display？

[WMinsane]

I want to validate default value of screen.
I use shouldValidate: "onBlur" option so I tried code below and it works.
But It looks bad . I'd like to know how to do it better.
useEffect(() => {
form.validate()
setTimeout(() => {
inputRef.current?.focus();
inputRef.current?.blur();
}, 200);
}, []);

you should be able to validate a field directly with form.validate({ name: fields.something.name }).

thank you for your replay.
Can that solution validate many fields?
I mean pass object and validate it in one line.

I forget that the name is optional on the validate intent. form.validate() should be enough if you wanna validate the whole form. You don't need to trigger any event from the inputs.
