    Class Level

    Represents a numbering level within an abstract numbering definition.

    This is the standard level definition used in abstract numbering definitions. Each abstract numbering definition can contain up to 9 levels (0-8).

    Reference: http://officeopenxml.com/WPnumbering-numFmt.php

    // Create a decimal numbered level
    const level = new Level({
      level: 0,
      format: LevelFormat.DECIMAL,
      text: "%1.",
      alignment: AlignmentType.LEFT,
      start: 1,
    });

    // Create a bullet level with custom styling
    const bulletLevel = new Level({
      level: 0,
      format: LevelFormat.BULLET,
      text: "\u2022",
      alignment: AlignmentType.LEFT,
      style: {
        paragraph: {
          indent: { left: 720, hanging: 360 },
        },
      },
    });

    Methods

    • Prepares this component and its children for XML serialization.

      This method is called by the Formatter to convert the component tree into an object structure compatible with the xml library (https://www.npmjs.com/package/xml). It recursively processes all children and handles special cases like attribute-only elements and empty elements.

      The method can be overridden by subclasses to customize XML representation or execute side effects during serialization (e.g., creating relationships).

      Parameters

      • context: IContext

        The serialization context containing document state

      Returns IXmlableObject | undefined

      The XML-serializable object, or undefined to exclude from output

      // Override to add custom serialization logic
      prepForXml(context: IContext): IXmlableObject | undefined {
        // Custom logic here
        return super.prepForXml(context);
      }
