The Tokens widget allows you to add shortcodes within the post text. As a result, you can show values from Post, Term, User, Date, WP_Query, System and Option.

Shortcode composition:
– [ (open tag);
– post (or user or option, required);
– : field name (required, native fields and meta are supported);
– : sub field key (optional and multiple, if field is array);
– | ID (optional, if omitted will take the current);
– ? Fallback text (optional, shown if field value is null);
– ] (close tag).
