Nested Lists

Nested lists express hierarchy by placing child items under a parent item. In Microsoft Learn Markdown, indentation defines the nesting level, and ordered and unordered list types can be combined; exact markup behavior remains platform-specific.

Quick answer

Use nesting only when items genuinely belong under a parent item, and follow the publishing system’s indentation/markup rules.

Important caveats

Hierarchy Boundary

A nested item should be subordinate to the parent item rather than merely the next item in sequence.

Platform Boundary

Indentation and marker behavior are authoring-system specific; Microsoft Learn Markdown is one documented implementation.
