  1. Label margins Ensure an adequate amount of whitespace surrounds your selection controls and labels to avoid overcrowding and enhance readability.

<aside> 💡 Tip: Too large margins make it hard for users to tell which label corresponds to which selection control, especially if the list of options is long.

  1. Lay out your lists vertically with one choice per line You can still use a horizontal layout, but your buttons and labels should be arranged so that users can tell without trouble which choice corresponds to which label.

  1. If possible, use radio buttons rather than drop-down menus Radio buttons reduce cognitive load by displaying all options permanently, enabling easy comparison for users. They are particularly user-friendly for individuals with difficulties in precise mouse movements.

  1. Make labels actionable Enhance usability by utilizing actionable labels for checkboxes and radio buttons. Actionable labels are clickable, allowing users to activate the selection by clicking anywhere within the label area.
