Inline dropdown states

Typography

All dropdown text should be set in sentence case, with only the first word in a phrase and any proper nouns capitalized. Dropdown menu option text should not exceed three words.

Element	Font-size (px/rem)	Font-weight	Type token
Label	12 / 0.75	Regular / 400	$label-01
Field text	14 / 0.875	Regular / 400	$body-compact-01
Menu option text	14 / 0.875	Regular / 400	$body-compact-01

Error message	12 / 0.75	Regular / 400	$label-01
