    <p>First, are you sure this is correct? The comment and code does not match .</p> <pre><code>// Returns a single List&lt;Widget&gt; with 2 Widgets in it... List&lt;List&lt;Widget&gt;&gt; widgetGroups = getWidgetGroups(); </code></pre> <p>Second, create a WidgetGroup class that will act as a container for a single WidgetGroup.</p> <pre><code>public class WidgetGroup { private String name; private List&lt;Widget&gt; widgets; public String getName() { return name; } public void setName(String name) { this.name = name; } public List&lt;Widget&gt; getWidgets() { return widgets; } public void setWidgets(List&lt;Widget&gt; widgets) { this.widgets = widgets; } } </code></pre> <p>This would be a valid JSON structure:</p> <pre><code>{ "widgetGroups" : [ { "widgetGroup": [ "widget": { "fizz": "Yes", "buzz": "Never", "foo": "Always" }, /*More widgets*/ ] }, /*More widget groups*/ ] } </code></pre> <p>Something like this should work:</p> <pre><code>Map&lt;String, List&lt;WidgetGroup&gt;&gt; widgetGroups = new HashMap&lt;String, List&lt;WidgetGroup&gt;&gt;(); WidgetGroup widgetGroup1 = getWidgetGroup(); // Just an assumption of one of your methods. WidgetGroup widgetGroup2 = getWidgetGroup(); // Just an assumption of one of your methods. List&lt;WidgetGroup&gt; widgetGroupList = new ArrayList&lt;WidgetGroup&gt;(); widgetGroupList.add(widgetGroup1); widgetGroupList.add(widgetGroup2); widgetGroups.put("widgetGroups", widgetGroupList); </code></pre> <p>Then you call <code>toJson()</code> on the map. </p>

Guidance
A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
