+    Installer Framework 3.1 introduces repository categories as a new feature. When
+    you use an installer that contains repository categories, you can select a category
+    by its display name, fetch its contents, and then select the included components for installation.
+
+    You can fetch the components from a category as follows:
+    \code
+    Controller.prototype.ComponentSelectionPageCallback = function()
+    {
+        var page = gui.pageWidgetByObjectName("ComponentSelectionPage");
+
+        // if CategoryGroupBox is visible, check one of the checkboxes
+        // and click fetch button before selecting any components
+        var groupBox = gui.findChild(page, "CategoryGroupBox");
+        if (groupBox) {
+            console.log("groupBox found");
+            // findChild second argument is the display name of the checkbox
+            var checkBox = gui.findChild(page, "Archive");
+            if (checkBox) {
+                console.log("checkBox found");
+                console.log("checkBox name: " + checkBox.text);
+                if (checkBox.checked == false) {
+                    checkBox.click();
+                    var fetchButton = gui.findChild(page, "FetchCategoryButton");
+                    if (fetchButton) {
+                        console.log("fetchButton found");
+                        fetchButton.click();
+                    } else {
+                        console.log("fetchButton NOT found");

+        }
