如何在wordpress中创建Redux Framework中的Repeater字段？

Repeater field plugin is purchased in Redux framework. But I am creating it as a custom filed .

I have created 3 fields(title, phone, Textarea) with add more and delete button. In this, I want to add upload button along with that three fields . But I failed to add upload button . I tried a lot but it's not working .

Can you please tell me what is the way to add upload image button in custom field extension.

$fields = array(
    'id'=>'multi-text',
    'type' => 'multi_text',
    'title' => __('Multi Text Option - Color Validated', 'textdomain'),
    'validate' => 'color',
    'subtitle' => __('If you enter an invalid color it will be removed. Try using the text "blue" as a color.  ;)', 'texdoma'),
    'desc' => __('This is the description field, again good for additional info.', 'redux-framework-demo')
    ),
);
