Hi everyone

As the subject, when I try to embed media to basic page content,
I can't intuitively recognize each existed post or tweet, because their thumbnail all the same image.
It could have been improper operation when I use it, wish that someone could tell me that.

Thanks.

here is the enviroment:
Lightning v8.x-1.03
php 7.0.4
Acquia Dev Desktop2

Hello all I am trying to add a query parameter to a menu link in Drupal 8 with the following code.

Hello,

In Drupal 8 is it possible to hide or reveal a block depending on ip address?

I'd like to only show the 'Log in' link when the site is accessed by staff onsite at work.

Thanks in anticipation.

Hello,

I have a website with two languages (English and French) and I would like the Language switcher block to show the languages shortened like this : "EN | FR" instead of "English | French"
I managed to "translate" "French" to "FR" and it's working everywhere fine.
But when i change "English" to "EN" it doesn't change the language swicher block, and almost nowhere ...

Any idea ?

I think I understood what is Ctools content type for panels is but I am not sure why to use it or when.
I found a tutorial that explain how to code one and I copied it to my drupal 8 site but I can`t find where do I use it or how?

I downloaded panels modules and all the needed modules and still couldn`t find the panels UI or where do I see the example "Ctools content type" I created (with the help of the tutorial).

I need to create one that send a http request to a site and receive a JSON reply and display this reply.

Please, HELP!
