Folding Elements: -oxy-foldable / -oxy-folded / -oxy-not-foldable-child

Used to configure whether or not the content of an element can be expanded or collapsed.

Oxygen XML Author Eclipse plugin allows you to declare some elements to be foldable. This is especially useful when working with large documents organized in logical blocks, editing a large DocBook article or book, for instance. Oxygen XML Author Eclipse plugin marks the foldable content with a small blue triangle. When you hover with your mouse pointer over this marker, a dotted line borders the collapsible content. The following actions are available in the Folding submenu of the contextual menu:
Toggle Fold
Toggles the state of the current fold.
Collapse Other Folds
Folds all the elements except the current element.
Collapse Child Folds
Folds the elements indented with one level inside the current element.
Expand Child Folds (Ctrl + NumPad+ (Command + NumPad+ on macOS))
Unfolds all child elements of the currently selected element.
Expand All
Unfolds all elements in the current document.

-oxy-foldable Property

This property defines whether or not the content for an element can be folded by the user. To define that an element's content can be folded, use the -oxy-foldable:true property.

-oxy-folded Property

This property is used in conjunction with the -oxy-foldable property and it defines the elements that are folded by default. To define an element to be folded by default, use the -oxy-folded:true property.
Note: Since the -oxy-folded property works in conjunction with the -oxy-foldable property, the -oxy-folded property is ignored if the -oxy-foldable property is not set on the same element.

-oxy-not-foldable-child Property

When collapsing an element, it is useful to keep some of its content visible (for example, a short description of the collapsed region). The -oxy-not-foldable-child property is used to identify the child element that is kept visible. As its value, it accepts an element name or a list of comma-separated element names. The first occurrence of each child element specified in the list of element names will be identified as the not-foldable child and displayed. If the element is marked as foldable (-oxy-foldable:true;) but it does not have the -oxy-not-foldable-child property or none of the specified non-foldable children exist, then the element is still foldable. In this case, the element kept visible when folded will be the before pseudo-element.

Example: Folding DocBook Elements

All the elements below can have a <title> child element and are considered to be logical sections. You mark them as being foldable leaving the <title> element visible.
set,
book,
part,
reference,
chapter,
preface,
article,
sect1,
sect2,
sect3,
sect4,
section,
appendix,
figure,
example,
table {
    -oxy-foldable:true;
    -oxy-not-foldable-child: title;
}
Note: The foldable, folded, and not-foldable-child properties are deprecated and the equivalent with the -oxy prefix should be used instead.
