# TreeSelect
The tree selector of the dropdown menu,
it combines the functions of components `el-tree` and `el-select`.
## Basic usage
Selector for tree structures.
:::demo
tree-select/basic
:::
:::tip
Since `render-after-expand` defaults to `true`,
the selected label name may not be displayed when echoing,
you can set it to `false` to display the correct name.
:::
## Select any level
When using the `check-strictly=true` attribute, any node can be checked,
otherwise only leaf nodes are supported.
:::demo
tree-select/check-strictly
:::
:::tip
When using `show-checkbox`, since `check-on-click-node` is false by default,
it can only be selected by checking, you can set it to true,
and then click the node to select.
:::
## Multiple Selection
Multiple selection using clicks or checkbox.
:::demo
tree-select/multiple
:::
## Disabled Selection
Disable options using the disabled field.
:::demo
tree-select/disabled
:::
## Filterable

`filterMethod` can custom filter method for data,
`filterNodeMethod` can custom filter method for data node.
:::demo

:::demo
