Drupal 8.x

I'm using drupal 8. I don't see a module or built in feature which would enabled alphabetical grouping by first letter of Title; ie an A B C bar at the top of a view, which would filter by the selection, and group by A B C?

Is it possible to present related content types or taxonomies with checkboxes at edit time rather than the textboxes which lookup matching entries?

Say I have a Direction taxonomy of

North
South
East
West

I have a list of values which categorize various content types. I will need to show either a key value or a name value for the entries, depending on the view. Examples:

N or North
S or South
E or East
W or West

Can a taxonomy have a 'key' and a 'name', or is it just 'name'?

In the example the first characters are unique, but some of the lists I have need key values that are multi-character, so I can't rely on using the first character of a taxonomy value only (if that is even possible).

On my main nav menu, I have a menu item with this kind of structure:

Add Content
---Add New Movie
---Add New Director

etc

I built a menu with a static list content types entries which have a url that points to whatever the url is for new "Movies" or whatever. It's fine for now...I might guess that there are several ways to accomplish this? Just for the sake of my learning curve, what other non-rocket science ways can this be done?

I'm going through the tutorial series at

something that is rather odd is that when he creates a custom content type, and checks the box for adding the custom content type to the Main Navigation menu, a new menu item is created in Main Navigation (earlier video than the one I linked to, probably).

Hi!

I have a trouble with custom compound field creation.

I need to create custom field type, that will contain two items:
-company name (text)
-company description (textarea with ckeditor).

I defined methods in field type file:
