Signal Forms: Mark all as touched when not hidden

[paulstelzer]

Which @angular/* package(s) are relevant/related to the feature request?

forms

Description

At the moment you can only mark all fields as touched when using the submit method. In our use case this will lead to undesirable behavior.

Eg. we habe two fields (subject and message). The message is hidden and will only be displayed when entering a subject first. If I tap on submit without entering anything, the subject has an error message. After adding a subject, the message will have the error immidiatly because through submit it was marked as touched (although it was hidden).

Proposed solution

Let the developer decide which fields to mark as touched or add an option to markAsTouched, but only mark visible fields as touched (ignore hidden fields).

Hi,
There is an existing PR that covers this feature and is currently under discussion.
See: #65694

@paulstelzer Please correct me if I misunderstand, but #65694 address a different issue than what you've described. You're requesting that submitting a form not mark hidden fields as touched, correct?

[paulstelzer]

@leonsenft You are correct. I only want to ignore hidden fields to mark as touched when submitting. Like you made in your PR :)
