What Is a Conditional Field and How Do You Use It?

A conditional field appears or disappears depending on what was answered elsewhere on the record. The person filling the form sees only what applies to their case.

What it fixes

Conditionals solve two problems at once: completion rates and data quality.

Long forms that people abandon partway
Fields left blank because they did not apply
Guessed answers to questions meant for another case
Cleanup work separating real answers from noise

Where conditionals apply

On forms, hiding questions that do not apply
On open cards, showing only what matters at the current phase
On card covers, controlling what appears on a Kanban card
On connected blocks, not just individual fields
On embedded content, so different cases see different material

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 field, and which value, triggers it.
Choose the logic: start hidden and reveal, or start visible and hide.
Use numeric thresholds where the rule depends on a value rather than a selection.

Why choose Jestor for adaptive forms?

Jestor applies the same conditional engine across public forms, internal cards, and board covers, so a rule learned once works everywhere rather than being reconfigured per surface.

Conditionals can also change a field's editability by state — a panel that was editable before approval can become read-only once the decision is made.

Frequently Asked Questions

Can conditions depend on a number?

Yes, a field can appear when a value crosses a threshold. See jestor.com.
