I have the following code with a working method responsible for editing the title of selected list item (the key of the array object) using the input. How can I divide the list .items-list (without CSS) so that there are 3 items in one row, while my code with editing still works?
Vue.component('item-list', {
template: '#item-list-template',
data() {
return {
items: [{
title: 'item 1'
},
{
title: 'item 2'
},
{
title: 'item 3'
},
{
title: 'item 4'
},
{
title: 'item 5'
},
{
title: 'item 6'
}
],
activeIndex: -1,
}
},
methods: {
onItemClick(index) {
this.activeIndex = this.activeIndex === index ? -1 : index;
},
setActiveItemValue(event) {
const foundItem = this.items[this.activeIndex];
if (!foundItem) return;
return this.items[this.activeIndex].title = event.currentTarget.value;
}
},
computed: {
activeItemValue() {
return this.items[this.activeIndex]?.title ?? '';
}
}
});
Vue.component('item', {
template: '#item-template',
props: {
isActive: Boolean,
title: String
}
});
new Vue({
el: '#app'
});li.active {
background-color: yellow;
}<script src="https://cdnjs.cloudflare.com/ajax/libs/vue/2.5.17/vue.js"></script>
<div id="app">
<item-list></item-list>
</div>
<script type="text/x-template" id="item-list-template">
<div>
<input type="text" placeholder="Edit selected items" :value="activeItemValue" @input="setActiveItemValue" />
<div class="items-col">
<ul class="items-list">
<item v-for="(item, i) in items" :key="i" :title="item.title" :isActive="activeIndex === i" @click.native="onItemClick(i)" />
</ul>
</div>
</div>
</script>
<script type="text/x-template" id="item-template">
<li class="item" :class="{ active: isActive }">{{ title }}</li>
</script>
<style>
.items-list {
display: flex;
}
</style>
