Hello Nima Ahrar,

Thank you for reaching out. I hope you're doing well.

Our form input fields include basic HTML validation for required fields such as mobile numbers and email addresses. However, if you require more advanced validation rules, you have the flexibility to implement custom JavaScript to handle your specific requirements.

Additionally, if you're using our SP Page Builder addon, you can override it to tailor the functionality further. Please refer to our documentation on addon overrides for detailed guidance: 🔗 How to Override SP Page Builder Addons

As we do not provide customization support, we recommend working with a developer who is comfortable with JavaScript and Joomla customization if you need help implementing this.

Best regards
