Create multi-column layouts

Learn how to create a multi-column layout with Autocomplete.

Improving the search experience often means adding several sources of data, such as in a federated search. Doing this in an organized and efficient way can be challenging. To make the most od larger display on devices such as desktops and tablets, you should display data in a multi-column layout. This lets users quickly browse search results and reduces scrolling.

Before you begin

This tutorial assumes the following requirements:

• An installation of the autocomplete-js package.
• A populated Query Suggestions index. If you don’t have one, create it first: you can use the example application credentials and index provided in this tutorial.
• Existing HTML with an input element where you want to insert the autocomplete drop-down menu.
• Frontend development experience with HTML, CSS, and JavaScript.

Starter code

This tutorial builds an Autocomplete app composed of two columns:

• A left column taking one third of the width which displays recent searches and Query Suggestions
• A right column taking up the rest of the space which displays products.

Create a file called app.js in your src directory and add this code to it:

JavaScript

import { autocomplete } from "@algolia/autocomplete-js";

import "@algolia/autocomplete-theme-classic";

autocomplete({
  container: "#autocomplete",
  openOnFocus: true,
});

This starter code assumes you want to insert the autocomplete into a DOM element with autocomplete as an id. Change the container to match your markup. Setting openOnFocus to true ensures that the drop-down menu appears as soon as a user focuses the input.

Two-column layout

With the render function of autocomplete-js, you can customize the panel rendering to create two or more columns.

JavaScript

import { autocomplete } from "@algolia/autocomplete-js";

import "@algolia/autocomplete-theme-classic";

autocomplete({
  container: "#autocomplete",
  openOnFocus: true,
  plugins: [],
  render({ render, html }, root) {
    render(
      html`<div class="aa-PanelLayout aa-Panel--scrollable">
        <div class="aa-PanelSections">
          <div class="aa-PanelSection--left"></div>
          <div class="aa-PanelSection--right"></div>
        </div>
      </div>`,
      root,
    );
  },
});

Add recent searches and Query Suggestions

Add the recent searches (with a limit of two recent searches) and Query Suggestions plugin (limiting the number of suggestions to seven) to the left column. This gives a total of nine items in the right column.

Then, retrieve the recent searches and query suggestions plugins sources in the render function using elements and add it to the left column.

JavaScript

// ...
import { createLocalStorageRecentSearchesPlugin } from "@algolia/autocomplete-plugin-recent-searches";
import { createQuerySuggestionsPlugin } from "@algolia/autocomplete-plugin-query-suggestions";
import { liteClient as algoliasearch } from "algoliasearch/lite";

import "@algolia/autocomplete-theme-classic";

// You can use the example application credentials in case you don't have your own yet.
// const appId = 'latency';
// const apiKey = '6be0576ff61c053d5f9a3225e2a90f76';
const searchClient = algoliasearch("YourApplicationID", "YourSearchOnlyAPIKey");

const recentSearchesPlugin = createLocalStorageRecentSearchesPlugin({
  key: "multi-column-layout-example",
  limit: 2,
});

const querySuggestionsPlugin = createQuerySuggestionsPlugin({
  searchClient,
  indexName: "autocomplete_demo_products_query_suggestions",
  getSearchParams() {
    return {
      ...recentSearchesPlugin.data.getAlgoliaSearchParams(),
      hitsPerPage: 7,
    };
  },
});

autocomplete({
  container: "#autocomplete",
  openOnFocus: true,
  plugins: [recentSearchesPlugin, querySuggestionsPlugin],
  render({ elements, render, html }, root) {
    const { recentSearchesPlugin, querySuggestionsPlugin } = elements;

    render(
      html`<div class="aa-PanelLayout aa-Panel--scrollable">
        <div class="aa-PanelSections">
          <div class="aa-PanelSection--left">
            ${recentSearchesPlugin} ${querySuggestionsPlugin}
          </div>
          <div class="aa-PanelSection--right"></div>
        </div>
      </div>`,
      root,
    );
  },
});

Create a “products” source

Add a source to retrieve and display the products in the right column.

Create a dynamic source using the getSources function and retrieve the products from your Algolia index with the getAlgoliaResults function.

JavaScript

// ...

autocomplete({
  container: "#autocomplete",
  openOnFocus: true,
  plugins: [recentSearchesPlugin, querySuggestionsPlugin],
  getSources({ query }) {
    return [
      // ...
      {
        sourceId: "products",
        getItems() {
          return getAlgoliaResults({
            searchClient,
            queries: [
              {
                indexName: "autocomplete_demo_products",
                params: {
                  query,
                  hitsPerPage: 4,
                },
              },
            ],
          });
        },
        // ...
      },
    ];
  },
  render({ elements, render, html }, root) {
    const { recentSearchesPlugin, querySuggestionsPlugin } = elements;

    render(
      html`<div class="aa-PanelLayout aa-Panel--scrollable">
        <div class="aa-PanelSections">
          <div class="aa-PanelSection--left">
            ${recentSearchesPlugin} ${querySuggestionsPlugin}
          </div>
          <div class="aa-PanelSection--right"></div>
        </div>
      </div>`,
      root,
    );
  },
});

Display products

Now that you’ve set up your source, you can display products with templates.

Create a product item component

Start by creating a file called ProductItem.js in your src directory, then copy and paste the following code (a component used to render each item of your source):

JavaScript

function cx(...classNames) {
  return classNames.filter(Boolean).join(" ");
}

function formatPrice(value, currency) {
  return value.toLocaleString("en-US", { style: "currency", currency });
}

export function ProductItem({ html, hit, components }) {
  return html`
    <a
      href="https://example.org/"
      target="_blank"
      rel="noreferrer noopener"
      class="${cx("aa-ItemLink", hit.objectID)}"
    >
      <div class="aa-ItemContent">
        <div class="aa-ItemPicture">
          <img
            src="${hit.image_urls[0]}"
            alt="${hit.name}"
            onLoad=${() => {
              const imgEl = document.querySelector(
                `.${hit.objectID} .aa-ItemPicture`,
              );
              imgEl.classList.add("aa-ItemPicture--loaded");
            }}
          />
        </div>

        <div class="aa-ItemContentBody">
          <div>
            ${hit.brand &&
            html`
              <div class="aa-ItemContentBrand">
                ${components.Highlight({ hit, attribute: "brand" })}
              </div>
            `}
            <div class="aa-ItemContentTitleWrapper">
              <div class="aa-ItemContentTitle">
                ${components.Highlight({ hit, attribute: "name" })}
              </div>
            </div>
          </div>
          <div>
            <div class="aa-ItemContentPrice">
              <div class="aa-ItemContentPriceCurrent">
                ${formatPrice(hit.price.value, hit.price.currency)}
              </div>
              ${hit.price.on_sales &&
              html`
                <div class="aa-ItemContentPriceDiscounted">
                  ${formatPrice(hit.price.discounted_value, hit.price.currency)}
                </div>
              `}
            </div>
            <div class="aa-ItemContentRating">
              <ul>
                ${Array(5)
                  .fill(null)
                  .map(
                    (_, index) =>
                      html`<li key="${index}">
                        <div
                          class="${cx(
                            "aa-ItemIcon aa-ItemIcon--noBorder aa-StarIcon",
                            index >= hit.reviews.rating && "aa-StarIcon--muted",
                          )}"
                        >
                          <svg viewBox="0 0 24 24" fill="currentColor">

              </ul>
              <span class="aa-ItemContentRatingReviews">

          </div>
        </div>
      </div>
    </a>
  `;
}

Render each source item

To render each source item, use the templates option in your source with the item function.

JavaScript

// ...

autocomplete({
  // ...
  getSources() {
    return [
      // ...
      {
        sourceId: 'products',
        getItems({ /_..._/ }) {
          // ...
        },
        templates: {
          item({ html, item, components }) {
            return ProductItem({ html, hit: item, components });
          },
        },
        // ...
      },
    ];
  },
  render({ elements, render, html }, root) {
    const { recentSearchesPlugin, querySuggestionsPlugin, products } = elements;

    render(
      html`<div class="aa-PanelLayout aa-Panel--scrollable">
        <div class="aa-PanelSections">
          <div class="aa-PanelSection aa-PanelSection--left">
            ${recentSearchesPlugin} ${querySuggestionsPlugin}
          </div>
          <div class="aa-PanelSection aa-PanelSection--right">
            ${products}
          </div>
        </div>
      </div>`,
      root
    );
  },
});

Add styles

Copy and paste the following CSS snippet in your src directory and call it style.css.

Next steps

This tutorial focuses on building a multi-column layout but you can improve it by:

• Adding more sources
• Reshaping and combine your sources
• Adding no-result states

For an example, this two-column layout implements these features.
