Focus first error

React chapter 71 · scrollIntoView + focus · source: common pattern · after failed submit

The problem

Submit fails. The invalid field is above the fold (or in another wizard step). A red banner at the bottom says "fix errors" and the user sees nothing to fix.

The pattern that fixes it

On invalid submit, find the first field with an error, element.scrollIntoView({ block: "center" }), then .focus(). RHF setFocus(firstName). Keep name/id wired (chapter 9) so you can query the node.
