Seeking assistance from the experts here to solve this particular issue.
I have a dataset that looks like this:
[
{
title: 'Header',
children: [
{
title: 'Paragraph',
children: [],
},
],
},
{
title: 'Container',
children: [
{
title: 'Paragraph',
children: [],
},
],
},
]
The desired output is to render this data in a list of <div> elements as follows:
<div class="sortable-item" data-depth="1" data-index="0">Header</div> <!-- Parent -->
<div class="sortable-item" data-depth="2" data-index="0">Paragraph</div> <!-- Child-->
<div class="sortable-item" data-depth="1" data-index="1">Container</div> <!-- Parent -->
<div class="sortable-item" data-depth="2" data-index="0">Paragraph</div> <!-- Child-->
I've tried creating a recursive component so far, here's what I have:
<template>
<template v-for="(item, index) in tree">
<div
class="sortable-item"
:data-depth="getDepth()"
:data-index="index"
:key="getKey(index)"
>
{{ item.title }}
</div>
<Multi-Level-Sortable
:tree="item.children"
:parent-depth="getDepth()"
:parent-index="index"
:key="getKey(index + 0.5)"
></Multi-Level-Sortable>
</template>
</template>
<script>
export default {
name: 'MultiLevelSortable',
props: {
tree: {
type: Array,
default() {
return [];
},
},
parentDepth: {
type: Number,
},
parentIndex: {
type: Number,
},
},
methods: {
getDepth() {
return typeof this.parentDepth !== 'undefined' ? this.parentDepth + 1 : 1;
},
getKey(index) {
return typeof this.parentIndex !== 'undefined' ? `${this.parentIndex}.${index}` : `${index}`;
},
},
};
</script>
It can be observed that there is a <template> as the root element along with a v-for, which are typically not recommended in Vue.js. How can I overcome this and achieve rendering the elements in the specified format mentioned above?
Note: I attempted using vue-fragment and achieved the desired structure, but faced compatibility issues when incorporating Sortable.js, where it did not recognize any of the .sortable-item elements.
Any guidance or suggestions would be highly appreciated! Thank you!
