How to add new fields to Magento 2 contact form?

To extend the functionality of the contact form in Magento 2, you can customize it by modifying the contact_index_index.xml and contact.phtml files or using a module like MagePlaza Custom Form or WebForms Pro. These allow you to add fields like dropdowns, file uploads, and checkboxes without heavy coding. While these customizations enhance user interaction, be mindful of performance—excessive fields or poorly optimized modules can slow down form submission. For data security, always validate inputs and ensure file uploads are restricted to safe formats. If you're also working on Shopify app development, similar functionality can be achieved through custom Shopify apps that enhance form handling.
