How do I add an empty field prompt?

Steve Goodwin_97k3jc

I've created a custom field that I'd like to add an empty field prompt to, just like that for the Description field (e.g., "Add a description..."):

For my field, where can I add the prompt text?

More info: the field's data type and renderer are exactly the same as the Description field.

Based on the screenshot, we’re looking at the view screen, where the default value is shown as None - this cannot be changed. However, you can hide the field when it’s empty by configuring the issue layout in Project settings.

In the field configuration, you can set a default value - but for a text field, this might not be ideal, since it would retain the same value if the user doesn’t update it.

Alternatively, you can make the field required, which will add a red asterisk next to it and force users to fill it out during issue creation.

If the field is only needed at a specific point (not nesesserly during creation), you can use a validator on a transition. This way, when the issue reaches that step, you can show a custom message explaining why the field must be filled.
I’ve added a validator on the issue creation transition as an example:

Note: You must make the field optional again in the field config - required field checks happen before transition validators are triggered.
