a couple of notes:
1. You can add a specific field’s class on this to differentiate start and end date placeholders, for example.
2. You can’t use the above with repeaters, and nothing I’ve been able to find short of either creating a new custom field or doing some complex render_field_settings and render_field hooks in functions can resolve this.
It will show the placeholder in the first repeater row, but not in the subsequent ones.
