I have created a custom composite element by cloning the example module of Drupal 8 Webforms. It has a radio button and 4 select boxes. So when clicking 'Add" button, another row is being created, and likewise a series of 10 clicks would make the page too lengthy.
I need to list out a selected element ( Product ) in another table beneath the custom composite, and hide the filled row when the 'Add' button is clicked.
Since I am relatively new to Drupal 8, I have no idea how to achieve this. I tried using computed twig to fetch the data from products table using the syntax
products is the key of the custom composite element &
product is the select field inside the composite element. I didn't receive any output following the above syntax.
Could anyone help me out here ?
