What it does

Sections that appear when they are relevant

Ask about a delivery address only once someone has said they want delivery. The form stays short for everyone who does not need the long version.

Deliveries you can gate

Run the CRM delivery only for enquiries above a certain size, or skip the mailing list unless the consent box is ticked.

Checked twice, for the same reason as validation

Conditions run in the browser so the form feels immediate, and again on the server so a hidden field cannot be submitted by editing the page.

Getting it working

01
Select a block

Choose the field or section you want to control, in the block editor.
02
Write the condition

Pick the field it depends on, the comparison, and the value.
03
Choose the effect

Show, hide or disable, and decide whether hidden answers are still submitted.

Every setting

What you can configure, and where it lives. Site settings apply everywhere; the rest are set on the form itself.

Setting	Scope	Notes
Subject	Per rule	The field the condition reads.
Comparison	Per rule	Equals, contains, greater than and so on.
Effect	Per rule	Show, hide or disable.
Delivery gate	Per delivery	Whether this delivery runs at all.

Questions

Ask support

Are hidden fields still submitted?

That is yours to choose per rule. The default is not to submit them, because a field someone never saw is rarely an answer they gave.

Can one field depend on several others?

Yes. Combine conditions with and / or.

Does it work across steps in a multi-step form?

Yes. A condition on step three can read an answer from step one.

What happens to validation on a hidden required field?

It is not enforced while the field is hidden, so a required question someone was never asked cannot block their submission.
