How to Use Conditional Fields in Forms

Conditional fields in forms show or hide a question depending on what was answered before. The respondent sees only what applies to them, and the data that comes back is cleaner because irrelevant fields are never filled.

Why long forms produce bad data

Every question a respondent does not understand is a chance for a wrong answer or an abandoned form.

Fields left blank because they did not apply
Guessed answers to questions meant for a different case
Abandonment partway through a form that felt endless
Cleanup work afterwards to separate real answers from noise

Where conditionals earn their place

Situation	What the conditional does
Rejection reason	Appears only when a request is marked refused
Company size branch	Routes to different follow-up content per segment
Phase-specific fields	Shows only what matters at the card's current stage
Threshold-based fields	Reveals extra detail when a value crosses a limit

How to configure it in Jestor

Open the Super Form editor in Jestor.
Select the field or block you want to control.
Set the condition — which other field, and which value, triggers it.
Apply conditionals to connected table blocks as well, not just simple fields.
Combine conditionals with phases so each stage of a Kanban shows its own fields.

Why choose Jestor for conditional logic?

Jestor applies conditionals across the whole form system: simple fields, blocks, connected tables, and open cards. The same rule that hides a field on a public form hides it inside the card an approver sees.

This is what keeps approval and request forms short. A cancellation reason appears when something is cancelled, and stays invisible the rest of the time.

Yes, a field can appear when a value crosses a limit you define.
