Tree
Lazy Branch Tree
A tree whose branch loads on first expansion rather than on render: while the request runs the branch is marked aria-busy and holds its space with three placeholder rows.
What you can change
- the tree contents and lazy branches through nodes
- the tree caption through label
- the simulated request delay through delay

For developers
The install command lives in the “Component source” block below — a signed link that stays valid for 24 hours.
Technical notes
The component is self-contained: one file, no dependencies, its own palette in the local --vibeui-tree-007-* variables. Client component: the sets of expanded and loading branches plus the cache of the children that arrived live in useState, and the timers that fake the request are collected in a ref and cleared on unmount. A branch with a lazy field loads once: the result goes into the cache, and expanding it again requests nothing. For the duration of the request the branch gets aria-busy and a group of three placeholders — without them the tree jumps to the height of the list that arrives. The branch row is a real button, so expansion works from the keyboard without a key handler of its own.
