Get the tree nodes as a flat array
tree.flat();
// [{...}, {...}, {...}, {...}]
Access nodes in tree
tree.elements[1].children[0].children[2];
// > CustomElementNode { id: 552255 tagName: "tree-item", ...}
Query trees in the node
const treeItem = tree.elements[1].children[0].children[2];
const otherTreeItem = tree.elements[1];
treeItem.isChildOf(otherTreeItem);
// true
otherTreeItem.isParentOf(treeItem);
// true
otherTreeItem.isSiblingOf(treeItem);
// false
Get children recursively
const treeItem = tree.elements[1].children[0];
treeItem.allChildren();
// [{...}, {...}, {...}, {...}]
