Helper text: Helper text appears below the label when the input is active. Helper text remains visible while the input is focused and disappears after focus away.

Error: Error messages appear below the input field and are always present while invalid.

Disabled: Disabled state should has a .not-allowed cursor on hover.

Typography

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

Structure

Dropdowns have two states, open and closed. An open and closed dropdown should be the same width and appropriately fit the design, layout, and content. The height of a closed dropdown stays consistent while the height of an open dropdown will vary based on the amount of options it has. Please note the various color differences for closed and open dropdowns.
