10+ Bootstrap Radio Buttons
This collection covers all methods for implementing single-option selection in Bootstrap: from classic forms to interactive cards. Standard .form-check classes and inline grouping are detailed, followed by creating segmented toggle buttons using .btn-group and .btn-outline-*. Advanced examples demonstrate using hidden radio buttons within clickable cards, allowing for complex content addition and visual highlighting of the selected element via border and background styles.
Examples

Bootstrap 5 Custom Radio with Product Box
An interactive shipping method selector implemented as a radio group where standard inputs are replaced by stylized cards. The selection logic relies purely on CSS sibling combinators (input:checked + label), triggering a border color change and the smooth appearance of a checkmark pseudo-element without JavaScript.
