How to auto-suggest rich content while searching in Google AMP?

CSS Web Development Front End Technology

To implement auto-suggestion of rich content while typing in an input field, we use the amp-autocomplete component from Google AMP. This component provides dynamic suggestions as users type, enhancing the search experience.

Required Scripts

To create auto-suggest functionality in Google AMP, you need to include these scripts

Installation: Add these script tags to your HTML <head> section to enable AMP autocomplete functionality.

<script async custom-element="amp-autocomplete" src="https://cdn.ampproject.org/v0/amp-autocomplete-0.1.js"></script>
<script async custom-element="amp-form" src="https://cdn.ampproject.org/v0/amp-form-0.1.js"></script>
<script async custom-template="amp-mustache" src="https://cdn.ampproject.org/v0/amp-mustache-0.2.js"></script>
<script async src="https://cdn.ampproject.org/v0.js"></script>

Basic Syntax

<amp-autocomplete filter="token-prefix" min-characters="1">
    <input type="search" name="query" />
    <script type="application/json">
        {"items": [...]}
    </script>
    <template type="amp-mustache">
        {{suggestion_template}}
    </template>
</amp-autocomplete>

Example: Rich Content Auto-Suggestions

Here's how to implement auto-suggestions with rich content including names and countries 

<!DOCTYPE html>
<html ?>
<head>
    <meta charset="utf-8">
    <script async src="https://cdn.ampproject.org/v0.js"></script>
    <script async custom-element="amp-autocomplete" src="https://cdn.ampproject.org/v0/amp-autocomplete-0.1.js"></script>
    <script async custom-element="amp-form" src="https://cdn.ampproject.org/v0/amp-form-0.1.js"></script>
    <script async custom-template="amp-mustache" src="https://cdn.ampproject.org/v0/amp-mustache-0.2.js"></script>
    <meta name="viewport" content="width=device-width,minimum-scale=1,initial-scale=1">

    <style amp-custom>
        .search-container {
            max-width: 400px;
            margin: 20px auto;
            padding: 20px;
        }
        input[type="search"] {
            width: 100%;
            padding: 10px;
            font-size: 16px;
            border: 2px solid #ddd;
            border-radius: 4px;
        }
        .suggestion-item {
            padding: 10px;
            border-bottom: 1px solid #eee;
            cursor: pointer;
        }
    </style>
</head>
<body>
    <div class="search-container">
        <form>
            <label>
                <span>Search for people:</span>
                <amp-autocomplete
                    filter="token-prefix"
                    filter-value="name"
                    min-characters="0">
                    <input type="search" name="query" placeholder="Type to search..." />
                    <script type="application/json">
                        {
                            "items": [
                                {"name": "Luffy", "country": "India"},
                                {"name": "Nami", "country": "USA"},
                                {"name": "Zoro", "country": "Canada"},
                                {"name": "Sanji", "country": "France"},
                                {"name": "Robin", "country": "Japan"}
                            ]
                        }
                    </script>
                    <template type="amp-mustache">
                        <div class="suggestion-item" data-value="{{name}}, {{country}}">
                            <strong>{{name}}</strong> - {{country}}
                        </div>
                    </template>
                </amp-autocomplete>
            </label>
        </form>
    </div>
</body>
</html>

A search input field appears with autocomplete functionality. When you start typing (e.g., "L" for Luffy), rich suggestions show both the name and country in a formatted dropdown list.

Key Attributes

Conclusion

The amp-autocomplete component provides powerful auto-suggestion capabilities for AMP pages. By combining JSON data with Mustache templates, you can create rich, interactive search experiences that enhance user engagement.
