What's the easiest way to create forms with skip logic in Angular?

• The easiest path depends on how much you want to own vs. hand off — here are the realistic options for Angular:

• Option 1: Angular's new Signal Forms (built-in, no dependency)

• Angular now ships a native hidden() rule as part of its Signal Forms API — you attach conditional logic declaratively via a schema, and fields that fail the condition are hidden and automatically excluded from validation. This is genuinely the "easiest" option if you're already on a recent Angular version, since there's nothing extra to install — skip logic is a first-class part of the framework now. You define rules against a FieldContext (accessing other fields' values via valueOf()/stateOf()), so "show question 5 only if question 2 = Yes" becomes a declarative rule attached to question 5's schema rather than manual *ngIf logic scattered through your template.

• Worth knowing: disabled, hidden, and readonly fields all skip validation automatically — so you don't need to manually guard validators for skipped questions, which is usually the fiddliest part of hand-rolling this. This is newer, so double-check it's stable in the Angular version you're targeting before committing a production form to it.

• Option 2: Reactive Forms (the established way, more boilerplate)

If you're not yet on Signal Forms, the standard pattern is: build your FormGroup/FormControl tree, subscribe to valueChanges on the controlling field, and conditionally show/hide dependent fields with *ngIf in the template while adding/removing validators programmatically (setValidators() / clearValidators() + updateValueAndValidity()) so hidden fields don't block submission.

• This works fine but is genuinely more manual than Signal Forms — you're wiring the "hide" and "don't validate" behavior yourself rather than getting it from a declarative rule.

• Option 3: SurveyJS (fastest if you want a full JSON-driven survey, not just a form)

• If what you actually want is a multi-page survey with skip logic (not just a form with a few conditional fields), SurveyJS has native Angular support and a mature branching-logic system where you define conditions on a JSON schema rather than writing any Angular-specific logic at all — the renderer handles showing/hiding/skipping pages based on prior answers.

• This is the least Angular-specific code you'll write, since the skip logic lives in the survey JSON, not your component — but it's a bigger dependency to bring in than the two options above if all you need is a handful of conditional fields.

Which to pick

A few conditional fields inside an otherwise normal Angular form → Signal Forms if available to you, otherwise Reactive Forms with valueChanges + validator toggling.

• A genuine multi-page survey/questionnaire with skip logic across many questions → SurveyJS — you'll write far less code than hand-building page-skip logic in raw Angular, at the cost of adopting their JSON schema and rendering model.

If you can tell me whether this is "a form with a couple of conditional fields" or "a full multi-step survey with several branch points," I can give you a more concrete code pattern for the right approach.
