/**
 * The Menu component displays a menu that lets the user choose a single value for a specific attribute.
 * @name Menu
 * @kind widget
 * @requirements The attribute passed to the `attribute` prop must be present in "attributes for faceting"
 * on the Algolia dashboard or configured as `attributesForFaceting` via a set settings call to the Algolia API.
 *
 * If you are using the `searchable` prop, you'll also need to make the attribute searchable using
 * the [dashboard](https://www.algolia.com/explorer/display/) or using the [API](https://www.algolia.com/doc/guides/searching/faceting/#search-for-facet-values).
 * @propType {string} attribute - the name of the attribute in the record
 * @propType {boolean} [showMore=false] - true if the component should display a button that will expand the number of items
 * @propType {number} [limit=10] - the minimum number of diplayed items
 * @propType {number} [showMoreLimit=20] - the maximun number of displayed items. Only used when showMore is set to `true`
 * @propType {string} [defaultRefinement] - the value of the item selected by default
 * @propType {function} [transformItems] - Function to modify the items being displayed, e.g. for filtering or sorting them. Takes an items as parameter and expects it back in return.
 * @propType {boolean} [searchable=false] - true if the component should display an input to search for facet values. <br> In order to make this feature work, you need to make the attribute searchable [using the API](https://www.algolia.com/doc/guides/searching/faceting/?language=js#declaring-a-searchable-attribute-for-faceting) or [the dashboard](https://www.algolia.com/explorer/display/).

 *
 * const searchClient = algoliasearch(
 *   'latency',
 *   '6be0576ff61c053d5f9a3225e2a90f76'
