Can someone explain the intended use of this field? What I was hoping it would do was for Link Type fields - whatever you put in the Placeholder field would be the Link Text - that would be a clickable link using the url entered for the field. But that isn’t it unfortunately.
Placeholder would need to be an actual value that matches the datatype. So in this example, it would need to be a default value for the link (not a label to overlay the link).
Happy to clarify. The placeholder is almost like tooltip. It is a greyed out bit of context in the background that is displayed in the value input box before the default is overriden with a unique value for that field. For example, if I wanted my PMs to populate this original end date field, I would set this placeholder during custom field creation.
Then when they were wondering which dates to consider, that greyed out background helper text from the placeholder would render in the project details drawer like this:
