    Widget

    Usage

    import { negativeRefinementList } from 'instantsearch-negative-refinement-list';

const search = instantsearch({
  indexName: 'indexName',
  searchClient: algoliasearch('appId', 'apiKey'),
});

search.addWidgets([
  negativeRefinementList({
    container: '#exclude', // Name of the widget container,

  }),
]);

search.start();

    Options

    This can be either a valid CSS Selector:

    negativeRefinementList({

    or an HTMLElement:

    negativeRefinementList({
  container: document.querySelector('#negative-refinement-list'),
  // ...
});

    required: true

    The name of the attribute to exclude from the results.

    negativeRefinementList({
  attribute: 'price',
  // ...
});

    Connector

    Usage

    import { connectNegativeRefinementList } from 'instantsearch-negative-refinement-list';

// 1. Create a render function
const renderNegativeRefinementList = (renderOptions, isFirstRender) => {
  // Rendering logic
};

// 2. Create the custom widget
const customNegativeRefinementList = connectNegativeRefinementList(
  renderNegativeRefinementList
);

// 3. Instantiate
search.addWidgets([
  customNegativeRefinementList({
    // instance params
  }),
]);

    Options

    items

    type: object[]

    The list of available items, with each item:

    • label: string: the label of the item.
    • value: string: the value of the item.
    • count: number: the number results matching this value.
    • isExcluded: boolean: whether or not the item is selected.
    const renderList = (items) => `
  <ul>
    ${items
      .map(
        (item) => `
        <li>
          ${item.isExcluded ? 'x' : ''} ${item.label} (${item.count})</button>
        </li>
      `
      )
      .join('')}
  </ul>
`;

const renderNegativeRefinementList = (renderOptions, isFirstRender) => {
  const { items } = renderOptions;
  const children = renderList(items);
  document.querySelector('#negative-refinement-list').innerHTML = children;
};

    widgetParams

    type: object

    All original widget options forwarded to the render function.

    const renderNegativeRefinementList = (renderOptions, isFirstRender) => {
  const { widgetParams } = renderOptions;
  widgetParams.container.innerHTML = '...';
};

// ...

search.addWidgets([
  customNegativeRefinementList({
    container: document.querySelector('#negative-refinement-list'),
    // ...
  }),
]);
