Drupal 8.x

On Drupal 8, when trying to save modifications of a certain content the following error message appear:

I have a Drupal 9 website with the default Drupla Olivero theme. When the navigation switches to mobile menu, I want the main menu to be unfolded. I need pure JS code. Drupal 9 no longer supports jQuery.

Here is the main menu collapse :

Here is the main menu unfold :

I activated the Olivero theme on Drupal 9.

I added the following code to my stylesheet to pin the navigation bar in mobile mode :

.site-header {
    z-index: 111;
    position: sticky;
    top: 0;
}

@media (min-width: 75rem) {
  body:not(.is-always-mobile-nav) .site-header {
    position: relative;
  }
}

Now I want to show a shadow below the navigation bar, when it is in mobile mode. I want the shadow to appear only when the user scrolls down the page. If down 1 pixel, the shadow should appear.

On Drupal 9, I have the Olivero theme. When the navigation switches to mobile mode, you have to go to the + button opposite the menu to display the sub-menu. It's not intuitive, because the user has to perform an additional action. I would like to unfold the main menu when the navigation switches to mobile mode.

I have a Drupal 9 website and the Geolocation Field module.

I created a view to show the nodes. My node type contains a "Geolocation" field.

I added to the view a "Filtering criteria" with "Content: Geolocation - Proximity (exposed)".

How do I sort view results? I want nodes to be displayed by creation date by default. I want if the user enters an address in the exposed filter, the nodes are sorted by proximity (nearest to farthest).
