I installed Drupal 8 manually (i installed Apache, PHP and MySql separately on Win 10) and i appended Drupal 8 to this install. I could start Drupal but i got the error: "Trusted host settings not enabled" and the warning: "PHP opcode not enabled". So i googled around and i uncommented

$settings['trusted_host_patterns'] = array(
'^www\.example\.com$',
);

in settings.php and i changed the pattern to my needs.

I also uncommented and altered:

opcache.enable=1

Hi Drupalists! 

I need to make an accordion to a page. Field group module is said to have a functionality to build accordions, but I don't seem to get it to work (= all I see is my defined fields and their titles, but the actual accordion functionality is missing). Could someone offer me some step by step instructions please? And if Field group is not the right/best way to build accordion, is there some other module for it? 

Many thanks and have a great weekend!

I want to display a few fieldgroups inside of a Paragraph side-by-side horizontally when in node edit form. I gave each fieldgroup the class .popular in the GUI in manage form display. The fieldgroup is of type Details. I added jquery wrap to a global js file that loads everywhere. I am using .ajaxStop because it works inside of Paragraphs after the ajax call.

(function ($) {
$(document).ajaxStop(function() {
$( ".popular" ).wrap( "<div class='col-md-4'></div>" );
});
})(jQuery);
