General discussion

I have a Drupal 10 installation with the Group module.

Here's what I'm looking to do:

It is possible to publish in groups, different type of content.

I want that when an authenticated user tags a group and the group posts a "News" content type, the user receives a notification email with the following message:

The group "GROUP NAME" released "NODE TITLE". You can consult the content on the link follow "NODE LINK".

How can I do this? Thanks for your help

What do you think about the idea to add menu badge on top of the profile window where avatar/image  is?

I wish it would be looking like this:

I'm creating an entry form and setting up my fields. One of these fields is set as a list (drop-down) with several character race types. Each race type has it's own description but how do connect the associated race description to the correct race, based on what is selected from the drop-down? The description is just a display, that gives more information about the race selected.

I've currently on have the Drupal 10 core installed without any additional add-ons.

When you edit a layout with the Layout Builder and add a body field for example (or other text fields), the preview is filled with dummy content, but instead or just a couple of line of text, it fills the whole page with dummy content. 

It makes it hard to move blocks up and down. 

Is there any way to limit this preview/dummy content characters? 

Thank you

The link of menu item has a possibility to apply attribute <button>.

What is the practical usage for that?

Enter <button> to display keyboard-accessible link text only.

I have views dropdown exposed filter with Search API form. Any idea how to make it like dropdown hierarchical collapsible menu?
Style doesn't matter.
The Better Exposed Filters does give such ability.
