# Builder Fields & Acai Attributes

## Field Types (`data-field-type`)

The builder uses `data-field-type` attributes on HTML elements to define editable areas.

| Type | Description | Returns |
|------|-------------|---------|
| `textfield` | Single line text | String |
| `headfield` | Heading text (generates `_tag` variable for semantic tag: h1-h6) | String |
| `textbox` | Multi-line text | String |
| `wysiwyg` | Rich text editor (HTML output) | HTML string |
| `link` | URL field (already includes slashes) | String |
| `upload` | Single image/file | Array: `[0].urlPath`, `[0].info1` (alt), `[0].info2-4` |
| `uploadMulti` | Multiple images | Iterable: `item.urlPath` |
| `list` | Dropdown (fixed options or from table) | String or foreign key num |
| `multiv2` | Repeatable group of fields | Array of objects |

### headfield Example

```html
<{{ title_tag | default('h2') }} data-field-type="headfield" class="text-3xl font-bold">
  Section Title
</{{ title_tag | default('h2') }}>
```

### upload Example

```html
<!-- Single image -->
<img data-field-type="upload"
     src="{{ image[0].urlPath }}"
     alt="{{ image[0].info1 }}"
     class="w-full rounded" />

<!-- Multiple images -->
<div c-for="photo in gallery">
  <img src="{{ photo.urlPath }}" alt="{{ photo.info1 }}" />
</div>
```

### list Example

```html
<!-- Fixed options -->
<select data-field-type="list" data-list-options="option1,option2,option3">
  <option>option1</option>
</select>

<!-- From table -->
<select data-field-type="list" data-list-table="categories" data-list-field="name">
  <option>Category</option>
</select>
```


## Acai Attributes

### `c-if` — Conditional Rendering

```html
<!-- Boolean check -->
<div c-if="showBanner">Banner content</div>

<!-- Equality check (uses = not ==) -->
<div c-if="layout = 'grid'">Grid layout</div>

<!-- Variable exists / is not empty -->
<div c-if="subtitle">{{ subtitle }}</div>
```

### `c-else`

Must immediately follow the `c-if` element:

```html
<div c-if="image">
  <img src="{{ image[0].urlPath }}" />
</div>
<div c-else>
  <p>No image available</p>
</div>
```

### `c-for` — Iteration

```html
<!-- Over array/multiv2 -->
<div c-for="item in record.features">
  <h3>{{ item.title }}</h3>
</div>

<!-- Over database table -->
<div c-for="product in products" c-where="active = 1" c-order="orden ASC" c-limit="6">
  <h3>{{ product.nombre }}</h3>
</div>
```

Available inside loop: `loop.index` (1-based), `loop.index is odd`, `loop.index is even`

### `c-class` — Dynamic CSS Classes

```html
<div c-class="{ 'bg-blue-500': isActive, 'text-white': isActive, 'hidden': !showElement }">
  Content
</div>
```

### `c-hidden` — Hidden Elements

Element is not rendered but can declare builder variables:

```html
<div c-hidden="true">
  <input data-field-type="textfield" value="default config value" />
</div>
```

### `c-required` — Conditional Required Fields

```html
<input type="text" name="company" c-required="userType = 'business'" />
```


## Forms (`c-form`)
