Layout
Groups, rows and the twelve-column grid.
Conditions
An element can follow what another one says. That is the difference between a form and a questionnaire that thinks along.
Customer type: Private
Customer type: Company
The condition sits on the "company data" row, not on the two fields inside it. Without reloading the page.
- 01
On the Structure tab click the name of the element that should only appear when needed, here the company data row.

In the element switch to the Conditions tab and click Add condition.
- 03
Pick the source under Field, the operator under Condition and enter the Value.
- 04
Click Save on the element and then Save at the top for the form.
Twelve operators, four groups
Which ones are on offer is decided by the type of the source, the field the condition looks at.

Several rules mean OR
One satisfied rule is enough for the element to appear. There is no AND. Whoever needs it builds the condition across two nested elements.
On rows and groups too
A condition on a row takes all the fields inside it along. That saves hanging the same rule on every single field.
Visible when in doubt
If a rule points at a field that no longer exists, the element counts as visible. A form changed later therefore does not break, at worst it asks for too much.
The same mechanism with a number
The rush notice in the demo form hangs on the rule "is greater than 7".
Planned quantity
250
Urgency 9
Preferred date
1 Jul 2026
For urgent requests we recommend adding a phone number.is greater than 7
On the rush notice pick the Field urgency under Conditions, the Condition is greater than and the Value 7.
The server evaluates the same conditions again before validation. A field that was invisible under the rules is therefore neither required as mandatory nor written into the submission, not even if somebody altered the form on the way.
