Right now, writing a custom composite element is best way to get a group of reusable elements.

Below are the two plugins and templates used to implement an Address element.

Hi, I have created two plugins and template to implement custom composite element.

  • Then I have created fields, but they are not showing up anywhere.
  • I have enabled the option for "Unlimited values - it still didn't show up.
  • And then I tried unlimited values in the table format. It worked.

What am I doing wrong? Why is it not showing up without table format?

Thanks!

You must configure and check 'Display elements in table columns'.

Yes, If I check the box "Display elements in table columns" - It is working perfectly fine.

If I do not check the box - Nothing is coming up., It's totally empty like blank screen

And even if I make it as "Limited" and number of values as "1" - It is showing up a blank screen.

@sattapuram You might need to slowly duplicate an existing composite element and figure out what is missing from your custom element.

I figured it out....It is because of the theme..
Reverting to the core theme solved the issue.

Thanks!!

@jrockowitz How do I include File upload field in my composite element?

I tried in different ways...the field is showing up but the file is nowhere saved/uploaded.

Complex elements (aka entity and file references) are not supported by composites without some hacking.

I am working on #2884624: Allow composite sub elements to be formatted which should help support complex elements with in composites.
