Dynamic placeholder text in 'Plain text' field type I have a plain text field that encourages content editors to write a more detailed description of a piece of content.

However, on the front-end the template will use the post title by default if this is not supplied.

I would like the placeholder text for this optional plain text field to represent the reality of this in the Dashboard - i.e. to display the title field as the placeholder if the field has not otherwise been used.

When editing the field, I have tried setting the 'Placeholder Text' as {title}, but this does not work - it displays "{title}"!

Is this possible? I don't want to create a new custom type of field as it seems a little heavy handed for this use case.

Yeah, those placeholder text fields aren't dynamically parsed as Twig templates like others (Entry URL Format, etc.).

Unfortunately that's all that is coming to mind for me for this use-case.
