Drupal 8.x

Good day

I want to create an app version of a website that's been developed in Drupal 8. What is the best way to do this?

I had a look at DrupalGap but seems that it's not being maintained or supported. The last update was in Nov 2017 and I don't get any feedback from the module developer.

Thank you.

Hello. I have a view with several elements and a panel with filters. Each element is associated with a taxonomy term (and only one). I want to make a view where items are grouped into categories. It should look like a heading and elements below it. About the same as done in VISA (https://developer.visa.com/apibrowser). How can i do this? I realized that I couldn't just copy views with different categories, because then the filters would stop working.

Hi! I’m trying to get a views tab to show up on only certain node types, for example:

I want ‘team tab’ to only show on content type ‘film’.

1. view path is film/%node/team, but the problem is that ‘tab team’ shows up on every other content type

2. when I add validation = content = film type, the tab still shows up on other content types, but with page not found which is rather unpleasant for the user.

I recently upgraded my drupal 8 site from 8.9.3 to 8.9.6. While testing, before moving to production, I noticed I'm getting the following error on my Calendar page if there is an event that spans multiple days.

"Warning: count(): Parameter must be an array or an object that implements Countable in Drupal\\calendar\\Plugin\\views\\style\\Calendar->calendarBuildWeekDay() (line 1258 of modules/contrib/calendar/src/Plugin/views/style/Calendar.php".

I had read where the issue might be related to PHP 7.2 so I've upgraded my PHP to 7.3, but I still get the same error.

Hello,

I have an html page that I wrote and I would like to use it.  I have have inserted the html with tags and everything into a new content page.  I changed the drop down of the text format to full html.  When I save it and preview it.  I get the html with tags being displayed not the interpreted html.

What am I missing?

How can I write raw html and php on the Drupal content page?

thanks,
