A simple organization structure tree view based on Vue3.x. It supports events, slots, horizontal vision and nodes manipulation

Usage

<template>
    <h1>Basic</h1>
    <div>
        <blocks-tree :data="treeData" :horizontal="treeOrientation=='1'"  :collapsable="true"></blocks-tree>
    </div>

    <h1>With slots</h1>
    <div>
        <blocks-tree :data="treeData" :horizontal="treeOrientation=='1'" :collapsable="true" :props="{label: 'label', expand: 'expand', children: 'children',  key:'some_id', onMove: onNodeMove, onMoveEnd: onNodeMoveEnd }">
        <template #node="{data,context}">
            <span>
                <input type="checkbox" :checked="selected.indexOf(data.some_id)> -1" @change="(e)=>toggleSelect(data,e.target.checked)"/> {{data.label}}
            </span>
            <br/>
            <span v-if="data.children && data.children.length">
                <a href="#" @click="context.toggleExpand">toggle expand</a>
            </span>

        <div>
        Selected: {{selected}}
