Hello Jaskier,
The “code” graphical component allows to use any Angular template. This means it can also use plain HTML.
To get the reference to the value of the variable, you need to use #ctx.value
Example:
{{ #ctx.value }}
the above statement will dynamically display the value of the variable inside an HTML paragraph tag.
Angular templates allow to have more complex behaviours, add some conditions, etc.
For more information on Angular templates, I suggest to checkout the official documentation:
