Drupal 8 is here and everyone is excited about it. There are too many features and add-ons to explore. However, this one focusses only on overlay / popup i.e. provide a simple and easy implementation. With this blog, I aim to explain the basic implementation of how to create a popup of your own.
Before learning to implement popup, let us briefly go through the drupal 8 routing system.
If you already know about the routing system, you can skip this section and if you don't I assume you still know at least the basics of Drupal 8. I have a page which has a table display of some data. On top of this page, I'll provide a link which will open a form in popup.
Now, let's start with the steps.
At first, we create a routing link where we show a table with some content.
_title: 'Movie List'
_permission: 'movies list'
