## Cascader
|
||
|
||
If the options have a clear hierarchical structure, Cascader can be used to view and select them.
|
||
|
||
### Basic usage
|
||
|
||
There are two ways to expand child option items.
|
||
|
||
:::demo Assigning the `options` attribute to an array of options renders a Cascader. The `props.expandTrigger` attribute defines how child options are expanded.
|
||
```html
|
||
<div class="block">
|
||
<span class="demonstration">Child options expand when clicked (default)</span>
|
||
<el-cascader
|
||
v-model="value"
|
||
:options="options"
|
||
@change="handleChange"></el-cascader>
|
||
</div>
|
||
<div class="block">
|
||
<span class="demonstration">Child options expand when hovered</span>
|
||
<el-cascader
|
||
v-model="value"
|
||
:options="options"
|
||
:props="{ expandTrigger: 'hover' }"
|
||
@change="handleChange"></el-cascader>
|
||
</div>
|
||
|
||

### Disabled option
|
||
|
||
Disable an option by setting a `disabled` field in the option object.
|
||
|
||
:::demo In this example, the first item in `options` array has a `disabled: true` field, so it is disabled. By default, Cascader checks the `disabled` field in each option object; if you are using another field name to indicate whether an option is disabled, you can assign it in the `props.disabled` attribute (see the API table below for details). And of course, field name `value`, `label` and `children` can also be customized in the same way.

||

<el-cascader :options="options"></el-cascader>

### Select any level of options
|
||
|
||
In single selection, only the leaf nodes can be checked, and in multiple selection, check parent nodes will lead to leaf nodes be checked eventually. When enable this feature, it can make parent and child nodes unlinked and you can select any level of options.
|
||
|
||
:::demo Set `props.checkStrictly = true` to make checked state of a node not affects its parent nodes and child nodes, and then you can select any level of options.

### Dynamic loading
|
||
|
||
Dynamic load its child nodes when checked a node.
|
||
|
||
:::demo Set `lazy = true` to use dynamic loading, and you have to specify how to load the data source by `lazyload`. There are two parameters of `lazyload`,the first parameter `node` is the node currently clicked, and the `resolve` is a callback that indicate loading is finished which must invoke. To display the status of node more accurately, you can add a `leaf` field (can be modified by `props.leaf`) to indicate whether it is a leaf node. Otherwise, it will be inferred by if has any child nodes.
|
||
```html
|
||
<el-cascader :props="props"></el-cascader>
|
||
|
||
<script>
|
||
let id = 0;

|

data() {

props: {

lazy: true,

lazyLoad (node, resolve) {
|
||
const { level } = node;
|
||
setTimeout(() => {
|
||
const nodes = Array.from({ length: level + 1 })
|
||
.map(item => ({
|
||
value: ++id,
|
||
label: `Option - ${id}`,
|
||
leaf: level >= 2
|
||
}));
|
||
// Invoke `resolve` callback to return the child nodes data and indicate the loading is finished.

||
resolve(nodes);

### Filterable
|
||
|
||
Search and select options with a keyword.
|
||
|
||
:::demo Adding `filterable` to `el-cascader` enables filtering. Cascader will match nodes whose label or parent's label (according to `show-all-levels`) includes input keyword. Of course, you can customize search logic by `filter-method` which accepts a function, the first parameter is `node`, the second is `keyword`, and need return a boolean value indicating whether it hits.
|
||

|
||
<div class="block">
