A repeater option would be handy when creating new widgets like Tabs, Carousel Images, Accordions, and so on.

The repeater option should allow us to create a group of options (Textbox, Image, Numberbox, Checkbox, etc.) just so we iterate through these options and "easily" show them in SE4.
In the example below, there is an array of fields, which contains the textbox and longtextbox options.

// Example of a widget.json file using the repeater
...
"description" : "tabsWidget.description",
"cache" : 0,
"version" : "1.0.0",
"displayConfig" : "modal",
"fieldsets" : [
{
    "title" : "tabsWidget.options.content.title",
    "options" : [
        {
            "id" : "repeater",
            "type" : "repeater",
            "label" : "Tabs",
            "attributes" : {
                "min" : 1,
                "max" : 4,
                "itemLabel": "Tab".
                "addMoreLabel" : "Add Tab",

As to test a Widget is needed it's better if only a code review is done, then we test the RepeaterOption in one of the new widgets: Tabs, Carousel, Accordion, etc.
