which method shows hierarchical data in a nested format?
The method that shows hierarchical data in a nested format is a tree (tree structure), typically visualized as a nested list or tree view in user interfaces.
Quick Scoop
When you have parent–child relationships (like folders and subfolders, categories and subcategories, or org charts), the standard way to show them is:
- A tree structure , where each node can have child nodes.
- Rendered in UI as:
- Nested unordered lists
<ul><li>…</li></ul>on the web.
- Nested unordered lists
* A tree view widget (e.g., jQuery TreeView, jsTree, or similar), which expands and collapses levels.
So if you see data indented level by level, like:
- Root
- Child 1
- Grandchild 1
- Child 2
- Child 1
…you’re looking at a hierarchical tree shown in nested form (nested lists / tree view).
