         }
      }

      "id": "myToggle",
      "features": {
         "show": {
            "onActions": [

            ]
         },
         "hide": {
            "onActions": [
               "hideContent"
            ]
         },
         "area": {
            "name": "content"
         }
      }
   }
]
"myToggle.content": [
   {
      "widget": "laxar-headline-widget",
      "features": {
         "headline": {
            "i18nHtmlText": "Content to show/hide"
         }
      }
   }
]

Use this configuration on a page to get a laxar-show-hide-widget instance.

In this example there are two AxHeadlineWidget which display a simple headline. The first headline is in the main widget area of the page and is visible all the time. The second headline is in the widget area of the laxar-show-hide-widget and can be shown or hidden.

The area provided by the laxar-show-hide-widget is named using its id and the configuration parameter area.name. The widget shows this area if it receives a takeActionRequest for one of the action configured under show.onActions and hides the area when it receives a takeActionRequest for one of the action configured under hide.onActions.

For full configuration options refer to the widget.json.
