How do I measure form field usages for text fields, checkboxes, radio buttons, multiselect fields?
The Form Analytics plugin for Matomo (Piwik) will automatically measure your form fields which includes all the standard form field types: text input fields, textarea, checkboxes, radio buttons, multiselect fields, and more.
Your form fields will be tracked automatically and there is nothing you have to do. Learn more in the Form Analytics user guide.
