Validate on initial render

[thaorell]

Hi,

my form (mode onBlur) has default values that are not valid. For example, the firstName default value is '', which is not validate under the validation schema, and therefore I want to gray out the Submit button on render. Is there a way to do that?

Hello!

First of all, your CSB has the beta release of RHF version 7 installed, which isn't recommended to use.

To check an empty string input as an invalid initial value, you should use required attribute instead of minLength. See this CSB with a working example

For more info you can check the HTML specs on minLength attribute

I completely overlooked that. Thanks
