Close one branch when other branch opened about react-treebeard

[brycejacobs]

Just do something like this:

function closeBranches(nodes){
    for(let i = 0; i < nodes.length; i++){
        const node = nodes[i]

        if(node.children && node.children.length){
            closeBranches(node.children);
        }

        node.toggled = false;
    }
}

You could also just set the current "cursor" field toggled, which you see in examples, to false before you set new cursor.
