Form Conditionals

Capabilities

• Show or hide fields and form blocks based on conditions
• Make fields required, optional, or read-only based on conditions
• Combine multiple rules within a single condition
• Group rules for more complex logic
• Set default fields that always follow a specific condition
• Add multiple independent conditions to the same form

How to configure

Step 1

Open Form Conditionals: In the Super Form editor, go to Form Tools and click Form Conditionals.

Step 2

Add default fields (optional): Under Default fields, click + Add existing field to select fields that will have a baseline behavior applied regardless of conditions. This is useful for fields you always want visible or required from the start.

Step 3

Add a condition: Under Set the conditions, click + Add condition. A condition panel will expand.

Step 4

Name the condition (optional): Type a name in the Condition name field to identify this condition. This is only for your reference inside the editor.

Step 5

Select the target: Open the Select fields or form blocks dropdown and choose which fields or form blocks this condition will act on.

Step 6

Select an action: Open the Select an action (Do) dropdown and choose what happens to the selected fields or form blocks when the condition is met. The available actions are:

• Hide — Hides the field or form block
• Show — Makes the field or form block visible
• Make required — Forces the user to fill in the field before submitting
• Make read-only — Displays the field but prevents the user from editing it
• Make optional — Removes the required constraint from the field
• Show and make required — Makes the field visible and required at the same time

Step 7

Define the rules (When): Under When, open the Select a field dropdown to choose which field triggers this condition. Then define the rule — such as the value it must have for the condition to activate. Click + Add rule to add more rules to the same condition, or + Add rule group to create a grouped set of rules with its own logic.

Step 8

Save: Click Done to close the condition panel, then click Save to apply all conditions to the form.

Keep in Mind

• Hiding a field does not clear its value — if a user previously entered data in a field that is then hidden, that value may still be submitted.
• A condition applies its action only when all defined rules are met.
• You can add multiple conditions to the same form — each one is evaluated independently.

FAQ

1 — Can I apply a condition to a form block, not just a field?

Yes. The Select fields or form blocks dropdown includes both fields and form blocks, so you can show or hide structural elements like sections and spacers based on conditions too.

2 — What is the difference between adding a rule and adding a rule group?

A rule is a single criterion (e.g., "field X equals Y"). A rule group lets you combine multiple criteria with their own AND/OR logic, enabling more complex conditions like "field X equals Y AND field Z is not empty."

3 — Can I have two conditions acting on the same field?

Yes. Multiple conditions can target the same field. If their rules conflict, the last matching condition takes effect.
