Module development and code questions

In bartik theme, the menu system does not display children of main menu even if they are created.

If a sub-menu is created , ie. sub menu of main home menu:

__ Main navigation : Name= Home; Enabled = true; Expanded = true

|__ _ Child menu: parent = Home; Enabled = true

Typical html from default drupal 8

Hi, 

I'm using Drupal 8.7.5 with Content Moderation module installed

When I published an article , then save this article back to draft,  when I update this article (draft) again, the node_field_data table won't change, only node_field_revision table will change(insert a new record).

This is not what I want, what I want is , no matter what state this article is, when I update this article, the node_filed_data table should change.

I guess this can be done by set the latest revision to be the default revision.

Hi, I have a Drupal 8.7 site with the Message module.

I copied the sub module Message Example to create my custom module.

THE CURRENT BEHAVIOR :

Users can subscribe (Flag module) to the following entities :

- Groups and receive a notification when a new node is created.
- Nodes and receive a notification when a new comment is created.
- Stores and receive a notification when a new product is created.
- Product and receive notification when a new comment is created.

Hello,

I am currently working on a headless drupal 8 project.

We are wanting to change the edit content page (an article for example) so that the view button at the top next to Edit, Delete, and Revisions, to point to somewhere other than the contents node, because our sites frontend is not handled by drupal, it is invalid and won't display correctly for the end user.

I looked at hooks, but as far as I can tell they only allow you to add content to the edit form.

I also tried looking for the twig template for that page but came up short.
