Cascader
Si las opciones tienen una estructura jerárquica clara, se puede utilizar Cascader para verlas y seleccionarlas.
Uso básico
Hay dos maneras de ampliar los elementos de opción hijos.
:::demo Asignar el atributo options a un array de opciones genera un Cascader. El atributo props.expandTrigger define cómo se expanden las opciones hijo.
<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>

Opción Disabled
Deshabilite una opción estableciendo el campo disabled en las opciones del objeto.
:::demo En este ejemplo, el primer ítem en el array options tiene un campo disabled: true, por lo que está deshabilitado. De forma predeterminada, Cascader comprueba el campo disabled en cada objeto de las opciones; si está utilizando otro nombre de campo para indicar si una opción está deshabilitada, puede asignarla en el atributo props.disabled (consulte la tabla de la API a continuación para obtener más detalles). Y por supuesto, el nombre de campo value, label y children también se pueden personalizar de la misma manera.

Carga dinámica
Carga dinámica de sus nodos hijos cuando se selecciona un nodo.
:::demo Establezca lazy = true para utilizar la carga dinámica, y deberá especificar cómo cargar la fuente de datos mediante lazyload. Hay dos parámetros de lazyload, el primer parámetro node es el nodo en el que se hace clic actualmente, y el resolve es una llamada de retorno que indica que la carga ha terminado y que debe invocarse. Para mostrar el estado del nodo con mayor precisión, puede añadir un campo leaf (puede ser modificado por props.leaf) para indicar si se trata de un nodo de hoja. De lo contrario, se deducirá verificando si tiene algún nodo hijo.
<el-cascader :props="props"></el-cascader>
<script>
let id = 0;
export default {
data() {
return {
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);
}, 1000);
}
}

Filtrable
Buscar y seleccionar opciones con una palabra clave.
:::demo Añadir filtrable a el-cascader permite el filtrado. Cascader hará coincidir los nodos cuya etiqueta o etiqueta de padre (de acuerdo con show-all-levels) incluya una palabra clave de entrada. Por supuesto, puedes personalizar la lógica de búsqueda mediante el filter-method que acepta una función, el primer parámetro es nodo, el segundo es keyword, y necesitas devolver un valor booleano que indique si da en el blanco.
