open

opens the branch with the specified id

id	id	the node id
show	boolean	if true, opens all parent of the branch

Example

tree = webix.ui({
    view: "tree",
    data: [
        { id: "branch1", value: "The Shawshank Redemption", data: [
            { id: "1.1", value: "Part 1" },
            { id: "1.2", value: "Part 2" }
        ]},
        { id: "branch2", value: "The Godfather", data: [
            { id: "2.1", value: "Part 1" }
        ]}
    ]
}); 
 
tree.open("branch1");

To learn when the open() call has completed loading dynamic data, you can set a promise in onDataRequest and check for it in onAfterOpen - see this example.
