Customizable components are key to any modern platform. Users have an expectation to be able to adapt and change their websites using recyclable design components part of their theme's system. Users should be able to edit their sliders or page layouts on the fly, moving and editing things freely as they need, without development experience.

It's something that services like **_Squarespace_** and **_Wix_** embrace. Even **_Wordpress_** is trying to implement a version of it with their _Gutenberg_ editor, and we've had it for years with the _WPBakery Page Builder_ (formerly _Visual Composer_) plugin.

> Websites are a collection of components, there's no reason we can't abstract control away from the code and in the reach of a click.

**Shopify** offers a version of this with their ' **snippets**'. A snippet is a reusable component that can be included in any template file. And on the frontpage of the website, you can use customizable snippets to compose a layout for the main landing page.

## How does it work?

On the frontpage it's a very similar process to something like _Squarespace_ or _Wix_. You have **_'content blocks'_** , each block is a **snippet** , and you arrange them in whatever order you'd like. If you click on a block, it reveals more options, like inserting text or images.

On any other page however, it still requires you to manually insert the include snippets into your Liquid page templates (`{% section 'your-snippet-here' %}`), and it doesn't offer the same level of customization. You can insert variables, but it's a different API than the block settings, so you'd have to account for that as well.

## Making the snippets

Creating a snippet is a snap. Open up your Shopify theme folder, navigate to the snippets folder, and create a new Liquid file with any HTML you'd like. This is great for components that repeat across the website, like newsletter blocks or sidebar widgets.

Here's an example of a block that contains a text header and a flex grid of boxes with images as background:

```
<div class="page-width">
  <div class="section-block">
      <div class="section-block __header section-block__ header--padded text-center">
        <h4 class="h1--mini section-block__title">Text columns with images</h4>
      </div>

    <div class="flex column-flex">
        <div class="flex__item column-overlay text-center">
            <noscript>
              <div class="column-flex__image" style="background-image: url(http://images.google.com/imageurl.jpg); background-position: center center;"></div>
            </noscript>
            <div class="column-flex__image lazyload"
              style="background-position: center center; background-image: url('http://images.google.com/imageurl.jpg);">
            </div>
          <div class="column-flex__content">
            <p class="h5">Image Title</p>
          </div>
        </div>
    </div>
  </div>
</div>
```

## West Code Customs

Customizing a snippet is where things get interesting. To make a snippet customizable, you have to add a **schema** to the bottom of the snippet. Copy and paste the following into the bottom of your current snippet:

```
{% schema %}
  {
    "name": "Text columns with images",
    "class": "index-section",
    "max_blocks": 24,
    "settings": [
      {
        "type": "checkbox",
        "id": "title_enable",
        "label": "Show header",
        "default": true
      },
      {
        "type": "text",
        "id": "title",
        "label": "Heading",
        "default": "Text columns with images"
      }
    ],
    "blocks": [
      {
        "type": "text_block",
        "name": "Text",
        "settings": [
          {
            "type": "text",
            "id": "title",
            "label": "Heading",
            "default": "Add a title or tagline"
          },
          {
            "type": "image_picker",
            "id": "image",
            "label": "Image"
          },
          {
            "type": "radio",
            "id": "image_align",
            "label": "Image alignment",
            "options": [
              { "value": "top center", "label": "Top center" },
              { "value": "center center", "label": "Center" },
              { "value": "bottom center", "label": "Bottom center" }
            ],
            "default": "top center"
          }
        ]
      }
    ],
    "presets": [
      {
        "name": "Overlay Columns",
        "category": "Text",
        "blocks": [
          {
            "type": "text_block"
          },
          {
            "type": "text_block"
          },
          {
            "type": "text_block"
          }
        ]
      }
    ]
  }
{% endschema %}
```

Once you add this to your snippet, if you go to your frontpage and click "Add Section", you should see the snippet title you defined in the list.

## What does the Schema mean?

The first chunk of JSON is pretty self explanatory. The **name** is the title you'll see in Shopify's backend. The **max\_blocks** limits the number of sub-components you can create (e.g.: a recent article snippet limited to 9 posts).

The **settings array** is where you put your top level configurations for the snippet. In this example, we give the user the type in their own header, and enable or disable the visibility of it.

The **blocks array** defines the extra _"sub-blocks"_ you can create within your content blocks, or snippet. In this example, we create a block where the user can define header text, upload an image, and pick the image alignment. Depending on the `max_blocks` defined earlier, you can make that many _"sub-blocks"_.

The **presets array** creates a "default" setup for your snippet. If the widget is 3 column and works best with 3 blocks, you can create 3 sample blocks. When the user creates a new snippet, the 3 sample blocks will be automatically created for them (filled with the defaultvalues you define).

## Adding the variables to your snippet

You can access top-level snippet configurations using `{{ section.settings.title | escape }}`, swapping title for the **ID name** of the desired setting. To get to block settings, you loop through the blocks and then access the for loop, like so:

```
{% for block in section.blocks %}
      {{ block.settings.title | escape }}
{% endfor %}
```

## If block contains variable, do something

When you combine the parameters you get from customization with Shopify's liquid templating system, you can achieve some fairly dynamic components with a minor tinkering. What happens if the user doesn't define any blocks? Or forgets to upload an image? We can handle all these conditional cases with Liquid's `{% if %}`.

**How do we handle the on/off toggles, like the header?**

Make a simple if statement checking for the variable. If it's switched to "on", the variable will be true, so any code inside will be executed:

```
{% if section.settings.title_enable %}
      {{ section.settings.title | escape }}
{% endif %}
```

**What if an image isn't defined?**

You can check for the variable and see if is equal (or in this case, not equal) to `blank`, a Shopify value that checks if the value is empty.

```
{% if block.settings.image != blank %}
      {{ block.settings.image | img_url: '600x600' }}
{% else %}
      <img src="Placeholder.svg" />
{% endif %}
```

**What if the user doesn't create blocks?**

The blocks variable contains a size attribute that lets you see how many blocks there are. You can check if it's equal to 0 in this case:

```
{% if section.blocks.size == 0 %}
      {% include 'no-blocks' %}
      {% comment %}
            We include a placeholder snippet that contains something like a statement saying "Sorry, no posts found".
      {% endcomment %}
{% endif %}
```

This also comes in handy if you need to check for grid consistency (e.g.: if blocks == 3, then do 3-column class attributes).

## The final code

When we string together a couple of simple if statements, and swap the hard-coded data with our Shopify snippet configuration variables, we have a fully customizable block:

```
<div class="page-width">
  <div class="section-block">
    {% if section.settings.title_enable %}
      <div class="section-block __header section-block__ header--padded text-center">
        <h4 class="h1--mini section-block__title">{{ section.settings.title | escape }}</h4>
      </div>
    {% endif %}

    <div class="flex column-flex">
      {% for block in section.blocks %}
        {% if block.settings.image != blank %}
          {% assign img_url = block.settings.image | img_url: '600x600' %}
        {% endif %}
        <div class="flex__item column-overlay text-center" {{ block.shopify_attributes }}>
          {% if block.settings.image != blank %}
            <noscript>
              <div class="column-flex__image" style="background-image: url({{ block.settings.image | img_url: '600x600' }}); background-position: {{ block.settings.image_align }};"></div>
            </noscript>
            <div class="column-flex__image lazyload"
              style="background-position: {{ block.settings.image_align }}; background-image: url('{{ block.settings.image | img_url: '300x300' }});"
              data-bgset="{% include 'bgset', image: block.settings.image %}"
              data-sizes="auto"
              data-parent-fit="cover">
            </div>
          {% else %}
            <div class="column-flex__image">
              <div class="placeholder-background">
                {{ 'placeholder.svg' | asset_url }}
              </div>
            </div>
          {% endif %}
          <div class="column-flex__content">
            <p class="h5">{{ block.settings.title | escape }}</p>
          </div>
        </div>
      {% endfor %}
    </div>

    {% if section.blocks.size == 0 %}
      {% include 'no-blocks' %}
    {% endif %}
  </div>
</div>
