Drupal 8.x

i m currently working on my first Drupal 8 site . We are almost ready to go in production, but i m facing a small but annoying problem. It seems like the breadcrumb hierarchy .

The problem:

If you browse between the pages you find in the head of the page  banner and breadcrumb the problem  in the 

display of the hierarchy of the breadcrumb   for exemple :

Home - services 

Home - service 1

Home - service 2

But i want the display be like :

Home - services 

Homes -services - service 1

Homes -services - service 2

Hello I have 2 taxonomy levels as show bellow

CityName1

3. advice

CityName2

1. News

How can I keep both levels in session when a user read different pages (/node/X) or taxonomy pages (/taxonomy/term/X)  and access it from a view ?

I use taxonomy to do this but I'm openmind to use another method. I don't have find any other solution .

Hello
I manage a holistic center website realized with Drupal 8

Various courses are held in the institute for which I have created a vocabulary called "category" with various terms: Ayurveda, Counseling, Meditation, Osteopathy, Yoga ...
I have created a "course" content type that has a "category" field of type "Entity Reference" to the "category" vocabulary.

I created a view to list all the courses that I created, sorted by "Category, Title"

Hi 

I am not sure where to install Drupal 8 using composer. There seems to be no reliable information on this topic. On my server I have the structure var/www/html and I have read instances where people have installed Drupal in either var/www or in var/www/html or even a subdirectory of var/www/html. It isn't clear if there is an ideal place to install Drupal with Composer. 

I have two sites including in my hosting plan.

One is Drupal 7 but I want to run the appropriate PHP version for the D8 site I am currently working on.

My question is, Would upgrading the PHP version to 7 in Cpanel for my D8 site cause issues with my D7 site? 

My hosting provider has advised that if I change the PHP version it will run on both sites as one is an addon domain. Is there a way around this, please?

I don't know php so I'm a little out of my depth here.

Kind regards

Amanda

I am using a sub theme of the bootstrap theme named 'tvb' but this problem seems to happen regardless of any theme I have tried, sun theme or otherwise.

system_menu_block:personal-goals

Upon inspecting the HTML output, it seems the heading_id is not being inserted within the id and aria-labelledby <nav> and <h2> elements:
