What is the method for utilizing vuedraggable in a grid comprising n x n cells?

edit

The method for utilizing vuedraggable in a grid comprising n x n cells involves creating a data array of size n x n and linking each cell in the grid to a corresponding element in the data array.

Then, the vuedraggable component can be used to allow users to drag and drop items within the grid. The data array will be updated with the new order of the grid after each drag and drop event.

To implement this, we can use a v-for loop to iterate over the elements in the data array and create a draggable element for each cell in the grid. We can also set the grid's display using CSS to create the desired layout.

Additionally, we can use the vuedraggable's sortable prop to ensure that items are only allowed to be moved within the grid and not outside of it.

Example code:

<template>
  <div class="grid-container">
    <div v-for="(cell, index) in gridData" :key="index" class="grid-item" vuedraggable="sortable">
      {{ cell }}
    </div>
  </div>
</template>

<script>
import draggable from 'vuedraggable'

export default {
  components: {
    draggable
  },
  data() {
    return {
      gridData: [
        [1, 2, 3],
        [4, 5, 6],
        [7, 8, 9]
      ],
      sortable: {
        group: 'grid',
        disabled: false,
        animation: 150
      }
    }
  }
}
</script>

<style>
.grid-container {
  display: grid;
  grid-template-columns: repeat(3, 1fr);
  gap: 10px;
}

.grid-item {
  background-color: #ddd;
  border: 1px solid #000;
  text-align: center;
  padding: 10px;
}
</style>
