I’m not sure if this would answer your question, but if you use HTML5 you can use the attribute placeholder

<input placeholder=“Placeholder”>

Hi, afaik there is no official way to add a placeholder to a field. You could file an improvement ticket in our JIRA, but I cannot guarantee if it will be picked up.
