Best regards,

Enable for Classic Editor

Enable for Block Editor

Show manual excerpt

Then you can show the manual excerpt with Content Views easily:

Notices

The manual excerpt is not enabled for Page by default. To enable manual excerpt for Page, please add this code to file functions.php in the theme’s folder:

/**
 * Enables the Excerpt meta box in Page edit screen.
 */
add_action( 'init', 'cvp_theme_add_excerpt_support_for_pages' );
function cvp_theme_add_excerpt_support_for_pages() {
	add_post_type_support( 'page', 'excerpt' );
}

Thank you,

Please select the option Allow all HTML tags in the dropdown in Display Settings >> Fields Settings >> Content.

With Content Views free

By default, these HTML tags are allowed in excerpt:
a, br, strong, em, strike, i, ul, ol, li.

To allow more tags, please add this code to file functions.php of your active theme:

/* CVP - allow other tags in excerpts */
add_filter( 'pt_cv_allowable_tags', 'cv_add_allowable_tags', 100, 1 );
function cv_add_allowable_tags( $args ) {
	$args[] = '<tag_1>';
	$args[] = '<tag_2>';
	return $args;
}

(replace tag_1, tag_2 with HTML tags you want to allow in excerpt).

Best regards,
