- * @param {*} props
+ * @param {*} props The component props.
+ * @param {Array} [props.options=[]] Array of options for the select dropdown. Each option should be an object containing `label` and `value` properties.
+ * @param {string} [props.className] Additional classname to further control the style of the component.
+ * @param {Function} [props.onChange=noop] Callback function triggered when the selected value changes. Receives the new value as an argument.
+ * @param {string} [props.value] The currently selected value. This component should be used as a controlled component. A special case is that after mounting, when `autoSelectFirstOption` is true and `value` is undefined, it tries to call back `onChange` once to select the first option so that the `value` can be consistent with the `<select>` element's own value.
+ * @param {boolean} [props.autoSelectFirstOption=false] If true, automatically triggers the onChange callback with the first option as value when no value is provided. If only one option is available, the select control is also changed to non-interactive.
+ * @param {*} [props.rest] Additional props passed to the `SelectControl` component.
