Customize the UI - connectMenu

If you want to create your own UI of the MenuSelect widget or use another UI library, you can use connectors.

Connectors are higher-order components. They encapsulate the logic for a specific kind of widget and they provide a way to interact with the InstantSearch context.

They have an outer component API that we call exposed props, and they provide some other props to the wrapped components which are called the provided props.

This connector is also used to build other widgets: Menu

It’s a 3-step process:

// 1. Create a React component
const MenuSelect = () => {
  // return the DOM output
};

// 2. Connect the component using the connector
const CustomMenuSelect = connectMenu(MenuSelect);

// 3. Use your connected widget
<CustomMenuSelect />

See code examples

Create a React component

const MenuSelect = ({
  object[] items,
  string currentRefinement,
  function refine,
}) => {
  // return the DOM output
};

Provided Props

If SEO is critical to your search page, your custom HTML markup needs to be parsable:

  • use plain <a> tags with href attributes for search engines bots to follow them,
  • use semantic markup with structured data when relevant, and test it.
