dbindly

List attributes allow you to render arrays of data by repeating HTML elements. Combined with filtering and sorting, you can create powerful dynamic lists.

dbind_repeat

Purpose: Repeat an element for each item in an array. This is essential for rendering lists, grids, and tables from your data.

Syntax:

<element dbind_repeat="arrayField">
  <!-- This entire element is repeated for each item -->
</element>

How It Works

DBindly finds the element with dbind_repeat
The element becomes a template
For each item in the array, a copy of the template is created
Inside each copy, data bindings refer to the current item

Basic Usage

<!-- Simple list -->
<ul>
  <li dbind_repeat="items" dbind_data="name"></li>
</ul>

Data:

{
  "items": [
    { "name": "Apple" },
    { "name": "Banana" },
    { "name": "Cherry" }
  ]
}

Result:

<ul>
  <li>Apple</li>
  <li>Banana</li>
  <li>Cherry</li>
</ul>

Accessing Item Properties

Inside a repeated element, use field names directly (no array notation):

<div dbind_repeat="products">
  <h3 dbind_data="name"></h3>
  <p dbind_data="description"></p>
  <span dbind_data="price" dbind_format="currency:USD"></span>
  <img dbind_src="image" dbind_alt="name">
</div>

Data:

{
  "products": [
    {
      "name": "Headphones",
      "description": "Premium wireless audio",
      "price": 149.99,
      "image": "/images/headphones.jpg"
    },
    {
      "name": "Keyboard",
      "description": "Mechanical RGB keyboard",
      "price": 89.99,
      "image": "/images/keyboard.jpg"
    }
  ]
}

Nested Properties

Access nested data within each item:

<div dbind_repeat="users">
  <h3 dbind_data="name"></h3>
  <span dbind_data="address.city"></span>
  <span dbind_data="address.country"></span>
  <img dbind_src="profile.avatar" dbind_alt="name">
</div>

Data:

{
  "users": [
    {
      "name": "John Doe",
      "address": {
        "city": "New York",
        "country": "USA"
      },
      "profile": {
        "avatar": "/avatars/john.jpg"
      }
    }
  ]
}

Special Loop Variables

Inside dbind_repeat, you can access special variables:

Variable	Description	Example
`_index`	Zero-based index (0, 1, 2, ...)	`{{_index}}`
`_number`	One-based number (1, 2, 3, ...)	`{{_number}}`
`_first`	Boolean, true for first item	`dbind_show="_first"`
`_last`	Boolean, true for last item	`dbind_show="_last"`
`_even`	Boolean, true for even indexes	`dbind_class="evenClass"`
`_odd`	Boolean, true for odd indexes	`dbind_class="oddClass"`

<div dbind_repeat="items">
  <span class="number">{{_number}}.</span>
  <span dbind_data="name"></span>
  <span dbind_show="_first" class="badge">First!</span>
  <span dbind_show="_last" class="badge">Last!</span>
</div>

Result:

<div>
  <span class="number">1.</span>
  <span>Apple</span>
  <span class="badge">First!</span>
</div>
<div>
  <span class="number">2.</span>
  <span>Banana</span>
</div>
<div>
  <span class="number">3.</span>
  <span>Cherry</span>
  <span class="badge">Last!</span>
</div>

Performance Considerations

Large Lists

For lists with many items:

Use Pagination: Break large lists into pages
Use Limits: Show initial subset with "Load More"
Virtual Scrolling: For very long lists, consider client-side virtual scrolling

<!-- Initial load with limit -->
<div id="items-container" dbind_repeat="items" dbind_limit="20">
  <div class="item" dbind_data="name"></div>
</div>
 
<button id="load-more" onclick="loadMoreItems()">
  Load More
</button>

Lazy Loading Images

Always add loading="lazy" to images in lists:

<div dbind_repeat="products">
  <img dbind_src="image" dbind_alt="name" loading="lazy">
</div>

Next Steps

Collections - Server-side data loading with pagination
Visibility - Conditional display
Formatting - Format values in lists
