Customize the UI - connectCurrentRefinements

If you want to create your own UI of the ClearRefinements 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: CurrentRefinements

It’s a 3-step process:

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

// 2. Connect the component using the connector
const CustomClearRefinements = connectCurrentRefinements(ClearRefinements);

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

See code examples

Create a React component

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

Provided Props

items
type: object[]

The currently applied filters. It is an array of objects with :

  • label: string: the label for the value.
  • attribute: string: the name of the attribute.
  • currentRefinement: any: the raw value of the refinement (depends on the widget).
  • items: object[]: a list of elements in case the refinement accepts multiple values (e.g. RefinementList).
  • value: function: the value to provide to therefine function to clear the refinement.

The value contains the argument to provide to the refine function for removing the refinement, label is for the display. When there are several refinements for the same attribute name, you get a nested items array that contains a label and a value, used to remove a single filter with refine. The attribute and currentRefinement properties are metadata containing the raw values.
