I recently had an issue with ckeditor inside pop-ups (modals) in drupal 8. This snippet is the solution to it.

I recently found out a bug I wasn't aware of. My default text format wasn't saved on a body field. I attached a snippet to fix this.

I've had some difficulties loading a list of translated terms. More in particular I didn't want to show the untranslated terms, but ONLY the ones that were already translated in the current language

A snippet with submitForm to redirect your form to another page and pass a variable.

With this snippet, you will be able to render a list of tags in drupal 8.

<p>I got this issue on a project I worked on. One answer: enable BigPipe module to fix this.</p>

By default, users with the permission of 'administer users' cannot assign roles on the user registration form. With this snippet you can, but make sure to hide the 'administrator'-role for your users.

I encountered this bug in a Display suite 2-column lay-out where I wanted the left region to disappear when empty. 

If you like to use the search api or a custom Views page for your search result I personally like to use the default search block and redirect it to my results page.

When creating custom blocks, sometimes you need to make sure the block is never cached f.e. when including dynamic links.
