Setting Up Conditional Logic

Key concepts

Before setting up conditions, it helps to understand two terms used throughout this article:

Parent element — the element whose answer triggers the condition. The data subject answers this element, and their answer determines whether the child element appears.
Child element — the element that is shown or hidden based on the parent's answer. By default it is hidden, and only appears when its conditions are met.

A parent element must always appear above its child element in the form.

Condition types

Each condition rule uses one of two matching types:

Type	The child element appears when…
Has some of	The data subject selects at least one of the specified answers
Has exactly	The data subject selects all of the specified answers and no others

Which elements can be a parent

Only the following element types can serve as a parent (condition source):

Element	Condition type
Country	Always "Has some of" — cannot be changed
State	Always "Has some of" — cannot be changed
Privacy right	Always "Has some of" — cannot be changed
Data subject	Always "Has some of" — cannot be changed
Multiple choice (custom)	Both "Has some of" and "Has exactly" are available

Which elements cannot have conditions applied

The following elements cannot be made into child elements — they are always visible on the form because their Required toggle is permanently enabled: Header, Country, Email, and Privacy right. An element that must always be shown cannot be made conditional.

Chaining conditions

An element can be both a parent and a child at the same time. For example, a State field can be shown only when Country = United States (making State a child of Country), and a follow-up question can be shown only when State = California (making that question a child of State). This creates a chain of conditions that narrows the form progressively based on the data subject's answers.

Multiple conditions on one element

A child element can have up to 10 conditions. When more than one condition is set, all conditions must be satisfied simultaneously — conditions are evaluated with AND logic. Within each condition, the answer matching follows the condition type (Has some of / Has exactly).

Adding a condition

Expand the element you want to show conditionally (the child element)
Click Add logic in the element's right sidebar
Select the parent element from the dropdown — only supported parent types that appear above the child are shown
Select the answer(s) that should trigger this element to appear
Select the condition type (Has some of or Has exactly)
Optionally click + Add rule to add another condition (up to 10)
Click Save draft to save your changes

Once saved, two indicators appear in the form to confirm the condition is in place:

On the child element: a numbered badge appears on the Edit logic button showing how many conditions are set on it
On the parent element: a blue banner appears reading "Other question(s) rely on this question for display logic"

Removing a condition

Click on Edit logic and click the remove icon next to any condition rule. If all rules are removed, the child element becomes unconditionally visible.

Things to keep in mind

If you reorder elements such that a child ends up above its parent, the condition is automatically removed. See Reordering Elements.
Conditions are evaluated live on the form — the child element appears or disappears instantly as the data subject makes their selections.
