Hello, Lanxiaodj,
We appreciate your prompt response.
It requests additional customization, which is out of our basic support scope.
For minor customization requests, we suggest considering paid customization services. You may submit a customization request to the Codeable team via their website: https://www.codeable.io/?ref=qGTdX
You are using the WPForms plugin, so we would recommend you contact support of the plugin. As we can see, your question is independent of our theme.
Provide URL of the demo from which you did this screenshot – https://prnt.sc/_7uRd__Gck5d We use MC4WP: Mailchimp for WordPress on our demos, and we can share custom code from there only.
Kind Regards,
8theme team
