Basic Show/Hide Rules

What Is Conditional Logic?

Conditional logic lets you create dynamic forms that change based on how a respondent answers. Instead of showing every field to every person, you can show or hide specific fields, sections, or pages depending on previous answers. This creates a more personalized experience and keeps your forms concise.

Common examples include:

  • Showing an "Other (please specify)" text field only when someone selects "Other" from a dropdown.
  • Hiding shipping address fields when a customer selects "Digital delivery."
  • Displaying follow-up questions only when a specific answer is given.

Creating Your First Rule

Follow these steps to set up a basic show/hide rule:

  1. Open your form in the editor and click on the field you want to conditionally show or hide.
  2. In the right-side settings panel, find the Logic tab.
  3. Click Add Condition.
  4. Configure the rule using three parts:
    • If: Select the field that triggers the condition (e.g., "How did you hear about us?").
    • Operator: Choose how the value is evaluated (e.g., "equals", "does not equal", "contains", "is not empty").
    • Value: Specify the answer that triggers the action (e.g., "Other").
  5. Set the Action to either Show this field or Hide this field.
  6. Click Save.

The If/Then Pattern

Every conditional rule in WittyForm follows an "if/then" pattern:

IF [field] [operator] [value], THEN [show/hide] [target field].

Here are some real-world examples:

  • IF "Employment Status" equals "Employed", THEN show "Company Name" field.
  • IF "Do you have dietary restrictions?" equals "Yes", THEN show "Please describe your restrictions" field.
  • IF "Country" equals "United States", THEN show "State" dropdown.

Available Operators

The operators available depend on the field type of the trigger field:

Text and Email Fields

  • equals: Exact match.
  • does not equal: Does not match the value.
  • contains: The answer includes the specified text.
  • does not contain: The answer does not include the text.
  • is empty: No answer provided.
  • is not empty: Any answer was provided.

Choice Fields (Dropdown, Radio, Checkbox)

  • equals: The selected option matches.
  • does not equal: A different option is selected.
  • contains: The selection includes the specified value (useful for multi-select fields).
  • does not contain: The selection does not include the specified value.
  • is empty: No option was selected.
  • is not empty: At least one option was selected.

Number Fields

  • equals: Exact number match.
  • does not equal: Different number.
  • greater than: Above a threshold.
  • less than: Below a threshold.
  • is empty: No value entered.
  • is not empty: A value was entered.

Multiple Conditions on One Field

You can add multiple conditions to a single target field. When you do, you choose how the conditions relate:

  • ALL conditions must be true (AND): The field is shown/hidden only when every condition is met.
  • ANY condition can be true (OR): The field is shown/hidden when at least one condition is met.

Testing Logic in Preview

Always test your conditional logic before publishing. Click the Preview button in the editor toolbar to open a live preview of your form. Fill out the trigger fields and verify that:

  • The target fields appear and disappear as expected.
  • The transitions are smooth (fields animate in/out).
  • Required validation still works correctly on conditionally shown fields.
  • Hidden fields do not submit data (WittyForm automatically excludes hidden fields from responses).

Tips and Best Practices

  • Hidden fields are not required: When a field is hidden by conditional logic, its "required" validation is automatically bypassed. You do not need to manage this manually.
  • Keep it simple: Start with basic show/hide rules and add complexity gradually. Overly complex logic can be hard to maintain.
  • Name your fields clearly: Descriptive field labels make it easier to set up and debug conditional rules.
  • Test every path: If your form has multiple conditional branches, test each one to make sure every user journey works correctly.
