orGenta Expanding Help
You can click on the + or - icon in front of a category to expand or collapse it. After you click on it, you can also press your arrow-right key to expand a Category, or your arrow-left key to collapse it. When you collapse a category and then expand it later, all of its subcategories retain their original expansion status. To collapse all subcategories of an Item use the menu option View, Collapse Node; if you want to completely expand a category along with all of its subcategories, use the menu option View, Expand Node.

Closed. After collapsing and expanding the parent, the frozen category
will appear purple in color, as the example Vegetables shows below:
