Compound Controls

User interface components that combine multiple interactive elements into a single logical control, such as a group of radio buttons, a set of checkboxes with a shared label, a combobox (combining a text input with a dropdown list), or a date picker with multiple fields. Compound controls present accessibility challenges because assistive technologies must convey both the overall group context (e.g., the question being answered) and the individual options within it. Proper implementation requires programmatic grouping using elements like fieldset/legend in HTML or appropriate ARIA roles (radiogroup, group) and labels so that screen readers can communicate the relationship between the group label and its constituent controls.
