Use the completed display demo as your reference. Here the labels are <span> elements (inline by default), while the trading note is also a <span>; set its display explicitly so it gets a full row. Hide only the organizer-only helper, not any essential instructions.
Checkpoint: previewing your styles should show two labels side by side and no helper text.
.tag to display: inline-block; so category labels can share a row..swap-note to display: block; so the note occupies a full row..hidden-helper to display: none; so the organizer helper is hidden.Use a separate rule for each class.
display: none removes the helper from the layout.
