Drupal 8.x

I have to filter out some view results programmatically because the filter is more complicated than what the build-in filter can handle. Now in the template file I've created for this view, it must display 3 items regardless of if 3 view result rows exist, if a view result row doesn't exist it displays a placeholder. 

I've been able to filter out the rows by creating a temp array and setting $view->result to that, however, after resetting the array keys to be a normal order (0, 1, 2, ...) the template file is unable to access those... 

Here's what my custom filter does

In the form of a content type called "Item" we would like each field data to be accompanied by contextual data about a) provenance (i.e. similar to academic reference with a note and a URL to a resource) and b) copyright information (i.e. another note and URL). This is like qualifiers for each piece of data. We are thinking of two ways of doing it:

I have installed and enabled the 'Responsive and off-canvas menu' module. I've also set up the dependencies and everything's good. The menu is working. However, the child items in the menu slides in from right; instead I want the child items to expand vertically (below the parent item). 

I looked at the mmenu.js documentation and they have an option to disable the 'slidingSubmenu' option. It works with the normal HTML setup but it's not working with Drupal menu's. 

Any idea how to make it work with Drupal 8.x? I'm kind of lost. Please share your experience/suggestions.

Hi, I am finding that when you have a multiple (unlimited) date field, you cannot remove, as offered by the button ‘clear’, in the popup.

Problem

When you have selected the unintented date, you are unable to clear the date in the popup ‘clear’.

Steps to reproduce

Create a date field with unlimited values

Then select one date that you want to empty, ‘clear’ does not remove the date in the popup.

I've newly installed drupal 8.9.6 (where there is no need to manually install composer as described here) and I'm now wondering why there is no Theme nor UI available...

What do I have to do, to get a nice, modern UI?
