Add post excerpt and date?

Since the plugin pulls results from Google Analytics directly and then tries to find a WordPress post to match, there isn’t a traditional loop. You can modify the list item output by doing something like the following:

function modify_gtc_list_item( $list_item_html, $page, $wppost ) {

	if ( isset( $wppost->ID ) ) {

		$excerpt = isset( $wppost->post_excerpt ) ? wpautop( $wppost->post_excerpt ) : '';
		$date = sprintf( '<span class="post-date">%s</span>', get_the_time( 'l, F j, Y', $wppost->ID ) );

		$to_add = $date . $excerpt;
		$list_item_html = str_replace( '</li>', $to_add . '</li>', $list_item_html );
	}

	return $list_item_html;
}

add_filter( 'gtc_list_item', 'modify_gtc_list_item', 10, 3 );

Than you ??

A last question,

If i wish to use the same widget in different widget area, each time to display the top post from a different category . . . . How can I achieve that ?

My back end skills are a bit limited, I Hope you understand,

THank you for all your time ??

The widget can be configured separately in each widget area you put it in.
