Yes it is possible to filter the excerpt using the filter – ‘lae_posts_grid_entry_excerpt’ provided by the plugin. You can have a look at an example at https://gist.github.com/live-mesh/90a79048686651fa0bfbf0eb40493611 on using filters in general with our plugin.
The premium version of the plugin has a checkbox to allow shortcodes and HTML on the excerpt. For the free version, since I haven’t tested it, can you pls check if the following code helps –
add_filter('lae_posts_grid_entry_excerpt', 'mytheme_shortcode_excerpt', 10, 2);
function mytheme_shortcode_excerpt($excerpt, $post_id) {
$output = '<div class="entry-summary">';
$excerpt_count = 120;
$post = get_post($post_id);
if (empty($post->post_excerpt))
$excerpt = $post->post_content;
else
$excerpt = $post->post_excerpt;
$output .= do_shortcode(force_balance_tags(html_entity_decode(wp_trim_words(htmlentities($excerpt), $excerpt_count, '…'))));
$output .= '</div>';
return $output;
}

hi, thanks for that, i had already solved it using the solution provided here (valid for all excerpts throughout the site).
i’ve read in force_balance_tags reference notes that “This function is not used for all WP pages due to bugs and performance issues”.
not sure the code below is less “expensive”, but it works:
/**
* allow formatted text in excerpts
**/
function better_trim_excerpt($text)
{
$raw_excerpt = $text;
if ( '' == $text ) {
$text = get_the_content('');
$text = strip_shortcodes( $text );
$text = apply_filters('the_content', $text);
$text = str_replace(']]>', ']]>', $text);
// Removes any JavaScript in posts (between <script> and </script> tags)
$text = preg_replace('@<script[^>]*?>.*?</script>@si', '', $text);
// Enable formatting in excerpts - Add HTML tags that you want to be parsed in excerpts, default is 55
$text = strip_tags($text, '<strong><b><em><i><a><code><kbd><p><br><ul><ol><li><img>');
// Set custom excerpt length - number of words to be shown in excerpts
$excerpt_length = apply_filters('excerpt_length', 60);
// Modify excerpt more string at the end from [...] to ...
// $excerpt_more = apply_filters('excerpt_more', ' ' . '...');
$words = preg_split("/[\n\r\t ]+/", $text, $excerpt_length + 1, PREG_SPLIT_NO_EMPTY);
if ( count($words) > $excerpt_length ) {
array_pop($words);
$text = implode(' ', $words);
// IMPORTANT! Prevents tags cutoff by excerpt (i.e. unclosed tags) from breaking formatting
$text = force_balance_tags( $text );
$text = $text . $excerpt_more;
} else {
$text = implode(' ', $words);
}
}
return apply_filters('wp_trim_excerpt', $text, $raw_excerpt);
}
// Remove the native excerpt function, and replace it with our improved function
remove_filter('get_the_excerpt', 'wp_trim_excerpt');
add_filter('get_the_excerpt', 'better_trim_excerpt');
Glad you found something that works for you. Thanks for posting here the solution – sure benefits others who are looking for a solution to this.
