To add a Summary widget, click on either the linked or inline widget button in the WYSIWYG editor and then choose “Summary” from the widget options. Next, use the content selector to choose an item or selection of items to be displayed. One can choose individual items at will. One can also choose paths and tags and include the items they contain or tag, respectively, by ticking the box under “Include Children” for that item in the content selector. In the next step, drag and drop your selected items into the order in which you’d like them to appear.
Finally, select your formatting options for the widget. If you’d like to include descriptive or explanatory text below the widget, choose “Custom text” under “Caption” and enter it there.
