    Hello,

    I´m trying to change childrens of a node with this code below:

    const selectedItem = this.tree.getItem($(‘#’ + id).get(0));
    const newItem = dataAdapter.records;
    const label = selectedItem.label;
    const childrenLevel = selectedItem[‘level’] + 1;
    const allItems = this.tree.getItems();
    // tslint:disable-next-line:max-line-length
    const removingItems = allItems.filter(item => item.parentElement !== undefined && item[‘level’] === childrenLevel && this.tree.getItem(item.parentElement).label === label);

    for (let i = 0; i < removingItems.length; i++) {
    this.tree.removeItem(removingItems[i].element);
    }

    this.tree.addTo(newItem , selectedItem.element);
    this.tree.refresh();

    The problem is that this works really slow. Is there any other solution?

    Thanks

    Hello pantxisto,

    Yes, this is the correct approach for changing children items.

    Another thing you can do, is just to update the source of the tree.
    Here is an Example.
