Tree

**Inherits:** :ref:`Control<class_Control>` **<** :ref:`CanvasItem<class_CanvasItem>` **<** :ref:`Node<class_Node>` **<** :ref:`Object<class_Object>`

Control to show a tree of items.

Description
-----------

This shows a tree of items that can be selected, expanded and collapsed. The tree can have multiple columns with custom controls like text editing, buttons and popups. It can be useful for structured displays and interactions.

Trees are built via code, using :ref:`TreeItem<class_TreeItem>` objects to create the structure. They have a single root but multiple roots can be simulated if a dummy hidden root is added.


.. tabs::

 .. code-tab:: gdscript

    func _ready():
        var tree = Tree.new()
        var root = tree.create_item()
        tree.hide_root = true
        var child1 = tree.create_item(root)
        var child2 = tree.create_item(root)
        var subchild1 = tree.create_item(child1)
        subchild1.set_text(0, "Subchild1")

 .. code-tab:: csharp

    public override void _Ready()
    {
        var tree = new Tree();
        TreeItem root = tree.CreateItem();
        tree.HideRoot = true;
        TreeItem child1 = tree.CreateItem(root);
        TreeItem child2 = tree.CreateItem(root);
        TreeItem subchild1 = tree.CreateItem(child1);
        subchild1.SetText(0, "Subchild1");
    }



To iterate over all the :ref:`TreeItem<class_TreeItem>` objects in a ``Tree`` object, use :ref:`TreeItem.get_next<class_TreeItem_method_get_next>` and :ref:`TreeItem.get_first_child<class_TreeItem_method_get_first_child>` after getting the root through :ref:`get_root<class_Tree_method_get_root>`. You can use :ref:`Object.free<class_Object_method_free>` on a :ref:`TreeItem<class_TreeItem>` to remove it from the ``Tree``.

Enumerations
------------

.. _enum_Tree_SelectMode:

.. _class_Tree_constant_SELECT_SINGLE:

.. _class_Tree_constant_SELECT_ROW:

.. _class_Tree_constant_SELECT_MULTI:

enum **SelectMode**:

- **SELECT_SINGLE** = **0** --- Allows selection of a single cell at a time. From the perspective of items, only a single item is allowed to be selected. And there is only one column selected in the selected item.

The focus cursor is always hidden in this mode, but it is positioned at the current selection, making the currently selected item the currently focused item.

- **SELECT_ROW** = **1** --- Allows selection of a single row at a time. From the perspective of items, only a single items is allowed to be selected. And all the columns are selected in the selected item.

The focus cursor is always hidden in this mode, but it is positioned at the first column of the current selection, making the currently selected item the currently focused item.

- **SELECT_MULTI** = **2** --- Allows selection of multiple cells at the same time. From the perspective of items, multiple items are allowed to be selected. And there can be multiple columns selected in each selected item.

The focus cursor is visible in this mode, the item or column under the cursor is not necessarily selected.

.. _class_Tree_constant_DROP_MODE_INBETWEEN:

enum **DropModeFlags**:

- **DROP_MODE_DISABLED** = **0** --- Disables all drop sections, but still allows to detect the "on item" drop section by :ref:`get_drop_section_at_position<class_Tree_method_get_drop_section_at_position>`.

\ **Note:** This is the default flag, it has no effect when combined with other flags.

- **DROP_MODE_ON_ITEM** = **1** --- Enables the "on item" drop section. This drop section covers the entire item.

When combined with :ref:`DROP_MODE_INBETWEEN<class_Tree_constant_DROP_MODE_INBETWEEN>`, this drop section halves the height and stays centered vertically.

- **DROP_MODE_INBETWEEN** = **2** --- Enables "above item" and "below item" drop sections. The "above item" drop section covers the top half of the item, and the "below item" drop section covers the bottom half.

When combined with :ref:`DROP_MODE_ON_ITEM<class_Tree_constant_DROP_MODE_ON_ITEM>`, these drop sections halves the height and stays on top / bottom accordingly.
