Get repeater item by itemId

I’ve been developing a plugin that creates elements using a repeater field, but rendered inside an SVG.

Since these elements are not directly on the first layer of the root element — they’re inside a foreignObject — they cannot be selected using :nth-child(number)....

In this case, I used the fieldId selector to target the repeaters, and it works perfectly on the frontend. However, in the Bricks editor, styles are always rendered directly on the main element — in this case, the repeater — ignoring the field selectors. For example:

$this->controls['widgetsRepeater'] = [
  'tab' => 'content',
  'group' => 'widgets',
  'label' => esc_html__( 'Repeater', 'bricks' ),
  'type' => 'repeater',
  'selector' => 'fieldId',
  'titleProperty' => 'title', // Default 'title'
  'imageSize' => [ 
    'label' => esc_html__('Image Size', 'bricks'),
    'type'  => 'number',
    'units' => true,
    'css' => [
      [
        'property' => 'height',
        'selector' => 'div.widget-image, img',
      ],
    ],
    'default' => '50px',
  ],
];
