Yes. Use the mctb_show_bar filter to control where the bar appears. This example shows it on blog posts only:
add_filter( 'mctb_show_bar', function( $show ) {
return is_single();
} );
This example shows it only on the contact page:
add_filter( 'mctb_show_bar', function( $show ) {
return is_page( 'contact' );
} );
See the WordPress Conditional Tags documentation for other conditions.
Yes. Add a name field and pass its value to the selected Mailchimp audience:
add_action( 'mctb_before_submit_button', function() {
echo '<input type="text" name="NAME" placeholder="Your name" />';
} );
add_filter( 'mctb_subscriber_data', function( $subscriber ) {
if ( ! empty( $_POST['NAME'] ) ) {
$subscriber->merge_fields['NAME'] = sanitize_text_field( $_POST['NAME'] );
}
return $subscriber;
} );
See adding a name field to Mailchimp Top Bar for more details.
Add this CSS to hide the bar on screens narrower than 600 pixels:
@media ( max-width: 600px ) {
#mailchimp-top-bar {
display: none !important;
}
}
The plugin keeps its front-end footprint small. Its JavaScript is under 2 kB when compressed, and the stylesheet loads without blocking page rendering.
