```html
<template>
<a-transfer
:dataSource="mockData"
:titles="['Source', 'Target']"
:targetKeys="targetKeys"
:selectedKeys="selectedKeys"
@change="handleChange"
@selectChange="handleSelectChange"
@scroll="handleScroll"
:render="item=>item.title"
>
</a-transfer>
</template>
<script>
export default {
data () {
const mockData = [];
for (let i = 0; i < 20; i++) {
mockData.push({
key: i.toString(),
title: `content${i + 1}`,
description: `description of content${i + 1}`,
disabled: i % 3 < 1,
});
}
const targetKeys = mockData
.filter(item => +item.key % 3 > 1)
.map(item => item.key);
return {
mockData,
targetKeys,
