Drupal 8.x

Hi Everyone.

I'm facing a weird problem for a few hours now, and I can't manage to find a way to solve this...

Here's the situation : I need to get all the content with a certain content type, assuming the content types list is something like an array :

$content_types = ['type1', 'type2', 'type3', 'type4'];

Hi everyone. I'm kinda new to Drupal and most things are still unclear to me. Currently I'm breaking my bead over the fact that I can't get my photo gallery and tags inline. This is the site I'm working on: http://altheercommunicatie.nl/node/74

Good morning

I am having a big problem with a newly created Drupal 8 site for a theater.

I think I'm misunderstanding how to get core optional js libraries to load on a page
I'm trying and failing to incorporate a JQuery UI slide effect

My hello_world.js is loading.
JQuery and JQuery.ui are loading
JQuery.effects.core and JQuery.effects.slide are not.
What am I doing wrong?

hello_world.libraries.yml

The scope is the following:

I have a view displaying informations, with multiples exposed filters setting as "block". I put the block form in the sidebar and it work. The form contains country and department displayed as select and a list of taxonomy displayed with checkboxes.
