Required Condition
1. Overview
Required conditions are a dynamic form validation mechanism that adjusts a field's required state based on specific conditions. When user operations or data states meet preset conditions, the system automatically marks fields as required or removes the requirement, improving user experience while ensuring data completeness.
2. Use Cases
- Condition-triggered Required: For example, when users select "Pickup", the delivery address field can be set as non-required; if "Express Delivery" is selected, the address field becomes required.
- Condition-exempted Required: For example, if users have filled in ID number, the passport number field can be set as non-required.
