How to toggle individual row details using Bootstrap-vue

Question

I'm using bootstrap-vue table for a project and got stuck on a problem with no documentation.

How can I toggle 1 row details at the time?

There is a complete table example here of a table with data on here

Answer 1

I'm using the v-model and setting it to a different array, as the v-model on b-table returns the currently shown items, after filtering and pagination. Making it more performance friendly as you're limiting the amount of items you gotta loop through to close.

window.onload = () => {
  new Vue({
    el: '#app',
    data() {
      return {
        items: [
          { id: 1, name: 'Povl', age: 26, gender: 'Male', secret: 'I love kittens' },
          { id: 2, name: 'Charlie', age: 9, gender: 'Female', secret: 'I love cupcakes' },
          { id: 3, name: 'Max', age: 71, gender: 'Male', secret: 'I love puppies' }
        ],
        currentItems: [],
        fields: [
          { key: 'name' }, { key: 'age' }, { key: 'gender' }, { key: 'actions' }
        ]
      }
    },
    methods: {
      //finds a specific item based on the provided ID and toggles details on that item
      toggleDetails(row) {
        if(row._showDetails){
          this.$set(row, '_showDetails', false)
        }else{
          this.currentItems.forEach(item => {
            this.$set(item, '_showDetails', false)
          })

          this.$nextTick(() => {
            this.$set(row, '_showDetails', true)
          })
        }
      }
    }
  })
}
