一、效果圖

二、參數(shù)配置

1、代碼示例

<t-antd-select
  v-model="selectVlaue"
  :optionSource="stepList"
  @change="selectChange"
/>

2、配置參數(shù)（Attributes）繼承 a-select Attributes

2-1、paginationOption配置參數(shù)（Attributes）繼承 a-pagination Attributes

3、繼承 a-select&&a-pagination events

三、源碼

<template>
  <div @mousedown="e => {
    e.preventDefault()
    selectOpen = true
  }" ref="main">
    <a-select
      class="t_select"
      v-model="childSelectedValue"
      :style="{width: width||'100%'}"
      :placeholder="placeholder"
      :open="selectOpen"
      @select="handleSelect"
      v-bind="attrs"
      v-on="$listeners"
      :mode="mode"
    >
