Hi @sovann,
They are different, the one in the template is just a template without functionality. You'll have to integrate your own functionality in the template since it's not only limited to Mailchimp. The template only provides the already styled elements. Unfortunately, we can't provide customization but if you prefer functionality first, then we recommend the EmailForms then just style it to display it inline.
To make your EmailForms inline, please add this CSS to your global custom CSS.
.tco-subscribe-form fieldset {
display: inline;
}
.tco-subscribe-form select, .tco-subscribe-form input[type="text"], .tco-subscribe-form input[type="email"] {
margin-bottom: 0px;
}
Thanks!
