Adding Show/Hide Conditions

This article walks through adding show/hide rules to an existing form. By the end you'll know how to chain conditions, group them, and avoid the most common pitfalls.

Step-by-Step

1. Open the form in the form builder.
2. Click on the field you want to conditionally show/hide. Look in the right-hand inspector for Conditions.
3. Click Add Condition.
4. Pick the trigger field, comparison operator, and value. Example: delivery_method equals international.
5. Choose the effect: Show or Hide. (Most rules are “Show when X”.)
6. Save the form.

Comparison Operators

• equals / not equals: Exact value match.
• contains / does not contain: Substring match — useful for tags or comma-lists.
• greater than / less than: Numeric comparison.
• is empty / is not empty: Branch on whether anything was entered.
• checked / unchecked: For boolean and checkbox fields.

Combining Conditions

You can combine multiple conditions with AND / OR. The rule builder groups conditions visually so you can see precedence.

Worked Examples

• Single condition: Show visa status when nationality is not UK.
• AND combination: Show parental consent when age < 18 AND activity type = physical.
• OR combination: Show fragile handling instructions when product category = glass OR product category = ceramic.
• Cascading: Field B appears when Field A = Yes; Field C appears when Field B = Some-value. Each tier is its own rule.

Tip: Avoid more than three levels of nesting. If you find yourself chaining four conditions to control a single field, consider splitting the form into multiple stages instead.
