Radio

Radio Field

The Radio field displays a list of options as radio buttons, allowing exactly one selection. Use it when you want all options visible at once rather than hidden in a dropdown.

switch ( $size ) {
    case 'small':

        $class = 'product-md';

Notes

• Behaves identically to Select in terms of return value — both return a single string
• Choose Radio over Select when you want all options visible without clicking a dropdown
• The returned value is the choice value, not the label
