Validations make sure users provide the right type of input before they can continue. This helps improve data quality, prevents errors, and ensures that the information you collect is usable.
For example, validations can require a properly formatted email address or make sure a specific input is not left empty (mandatory).
đź’ˇNote: All Input and Choice types in LanderLab support validation checks.
Where to find it :
- First, select the block where you want to apply a validation.
- In the block settings, you’ll find the Validation section.
How to Use Validations
By default, validations are set to off, but you can turn them on with a simple click in the block settings.
Right under that, you’ll find an Error Message input field. Here you can write the custom message that will appear if the validation is not met.
- If you don’t provide your own message, the system will automatically show the default: “This field is required.”
💡 Tip: Use short, clear messages (e.g., “Enter a valid phone number”) so users immediately understand what they need to correct.
