Best Practices

1. Group Related Settings with Headers

{
  "settings": [
    {
      "type": "header",
      "content": "Content Settings"
    },
    {
      "type": "text",
      "id": "heading",
      "label": "Heading"
    },
    {
      "type": "header",
      "content": "Layout Settings"
    },
    {
      "type": "select",
      "id": "columns",
      "label": "Columns"
    }
  ]
}

2. Always Provide Defaults

{
  "type": "text",
  "id": "heading",
  "label": "Heading",
  "default": "Default Heading"  ← Always provide!
}

3. Add Info Text for Complex Settings

{
  "type": "range",
  "id": "products_count",
  "label": "Number of Products",
  "min": 2,
  "max": 12,
  "default": 4,
  "info": "Maximum number of products to display from the selected collection"
}

4. Use Appropriate Input Types

• Text/numbers → text, textarea, number, range
• True/false → checkbox
• Multiple options → select, radio
• Resources → collection, product, image_picker
• Colors → color, color_background

5. Set Reasonable Limits

{
  "type": "range",
  "id": "padding",
  "min": 0,        ← Minimum value
  "max": 100,      ← Maximum value
  "step": 4,       ← Increment
  "default": 40    ← Sensible default
}

6. Include Presets for Quick Setup

{
  "presets": [
    {
      "name": "Section Name",
      "settings": {
        "heading": "Default Heading",
        "show_feature": true
      },
      "blocks": [
        {
          "type": "block_type"
        }
      ]
    }
  ]
}

Create schemas that make section customization intuitive and efficient for merchants.
