Hello,
If you are using the free version of the plugin (that was implemented to create form to estimate services and products costs, and other forms that not require server side processing), it does not includes the server side modules for processing the data collected through the form, and send the notification emails, it is the reason why the free version of the plugin has disabled the attribute: “Display submit button?” in form’s settings.
However, you can insert a submit button in the forms created with the free version of the plugin in multiple ways:
– Insert a common button field with the following code as the onclick event:
jQuery(this).closest('form').submit();
– Insert a “HTML Content” field in the form with the tag for the submit button as its content:
<input type="submit" name="send" value="Submit the Form" />
But as I said previously, using the free version of the plugin you should intercept the data submitted by the form, and process them by yourself.
Best regards.
