Printing rendered fields in your custom Paragraphs template using Twig is super easy.

Exactly as you would in a node template, you can print all rendered content using the {{ content }} variable:

{{ content }}

To print the rendered value of a specific field, you would use:

{{ content.field_custom }}

If you need to check whether the field actually has a value, you should use this syntax:

{% if content.field_custom|render %}

{{ content.field_custom }}

{% endif %}

But what if you need to access the raw value, without any additional field markup? That's easy, just use the following syntax:

{{ content.field_custom.0 }}
