What is the process for incorporating a particular item into a child's possession?

I've got a structure that looks like this:

items: [
                {
                    title: 'Parent',
                    content: {
                        title: 'Child1',
                        content: [
                            {
                                title: 'Child2',
                                content: {
                                    newFea: 'Child3'
                                },
                            },
                            {
                                title: 'Child2',
                                content: {
                                    newFea: 'Child3'
                                },
                            },
                            {
                                title: 'Child2',
                            },
                            {
                                title: 'Child2',
                                content: {
                                    newFea: 'Child3'
                                },
                            },
                            {
                                title: 'Child2',
                            }
                        ]
                    },
                },
         



 ],

On the front end, each Child2 has its own button. When the button is clicked, I wish to include Child3 in their content using { newFea: '' }.

Any suggestions on how I can accomplish this?

In the process of rendering UI using an array, it is important to utilize indexes as the dataset. These indexes should include all parent indexes leading up to the current child, as well as the index of the current child itself.

Upon clicking the button, split the indexes into an array of indices. Then, iterate through the array to identify which child2 has been clicked. Once identified, insert a child3 into that specific location and proceed to rerender the UI.

If you are utilizing Vue.js for your front end development, chances are you are employing the v-for directive to efficiently render lists.

<li v-for="(item, index) in items"> </li>

In the example above, take advantage of the index property within the callback function to transmit an index prop to your component when rendering:

<MyComponent
  v-for="(item, index) in items"
  :index="index"
   :key="item.id"
/>

Within your component, utilize the onClick event handler of your button to retrieve the index of that specific component and append a new child to the original object.

props:{
  index: Number
}
methods: {
  onclick(event) {
   // The following line might vary based on how 'items' is passed into this component
    items[0].content[index].content = { newFea: 'Child3' }                               
 },
}
