Mastering Choices.js: Limit the Displayed Search Results to 10 (minimum) with Ease

Setting Up Choices.js

Before we dive into limiting search results, let’s cover the basics of setting up Choices.js. You can include Choices.js in your project by either downloading the library or using a CDN:

// Using a CDN
<script src="https://cdn.jsdelivr.net/npm/[email protected]/dist/choices.min.js"></script>

// Downloading the library
<script src="choices.min.js"></script>

Once you’ve included Choices.js, create a container element for your search input:

<div id="search-input"></div>

Now, initialize Choices.js by creating a new instance and passing the container element as an argument:

const choices = new Choices('#search-input', {
  searchEnabled: true,
  searchChoices: ['apple', 'banana', 'orange', 'grape', 'kiwi'],
});

Limiting Search Results with Choices.js

To limit the displayed search results to 10 (minimum) using Choices.js, you can use the `searchResultLimit` option. This option allows you to set a maximum number of search results to display. If you want to set a minimum number of search results, you can use the `searchFloor` option in conjunction with `searchResultLimit`.

Here’s an updated initialization code snippet that limits the search results to 10 (minimum):

const choices = new Choices('#search-input', {
  searchEnabled: true,
  searchChoices: ['apple', 'banana', 'orange', 'grape', 'kiwi', 'strawberry', 'pineapple', 'peach', 'cherry', 'lemon', 'lime', 'mango', 'papaya'],
  searchResultLimit: 10,
  searchFloor: 10,
});

In this example, we’ve set `searchResultLimit` to 10, which means Choices.js will display a maximum of 10 search results. We’ve also set `searchFloor` to 10, which ensures that at least 10 search results are displayed, even if there are fewer matches.

Customizing the Search Results

Choices.js provides several options for customizing the search results. Here are a few examples:

Filtering Search Results

You can filter search results using the `searchFilter` option. This function allows you to filter out unwanted search results based on your custom logic.

const choices = new Choices('#search-input', {
  searchEnabled: true,
  searchChoices: ['apple', 'banana', 'orange', 'grape', 'kiwi', 'strawberry', 'pineapple', 'peach', 'cherry', 'lemon', 'lime', 'mango', 'papaya'],
  searchResultLimit: 10,
  searchFloor: 10,
  searchFilter: (choice, searchString) => {
    return choice.includes(searchString) && choice.length > 5;
  },
});

In this example, we’ve implemented a simple filter that only includes search results that contain the search string and have a length greater than 5 characters.

Displaying Custom Search Results

You can customize the display of search results using the `renderChoiceLimit` option. This function allows you to customize the HTML content of each search result.

const choices = new Choices('#search-input', {
  searchEnabled: true,
  searchChoices: ['apple', 'banana', 'orange', 'grape', 'kiwi', 'strawberry', 'pineapple', 'peach', 'cherry', 'lemon', 'lime', 'mango', 'papaya'],
  searchResultLimit: 10,
  searchFloor: 10,
  renderChoiceLimit: (choice) => {
    return `<div><span>${choice}</span></div>`;
  },
});

In this example, we’ve implemented a custom render function that wraps each search result in a `
