In this episode, we tackle the next step of our comment system: actually displaying comment replies underneath the parent comments. Up to this point, we could reply to comments, but we really weren't seeing those replies show up anywhere!
We walk through how to output replies directly below the parent comment by iterating through each comment's children and rendering them using the same comment item component. No need to reinvent the wheel or make a separate component—unless we need some extra functionality down the line!
You'll see how we add a check for child comments, add some margin to visually indicate nesting, and then use a loop to render each reply. We also talk about the importance of keys for Livewire so updates happen smoothly.
By the end, you get to see the replies show up in the browser in real time, using exactly the same style and features because we're reusing our existing comment component. There's a side note: currently, this could potentially allow infinite nested replies—which we'll address in a future episode. But for now, you can post replies and see them appear immediately, complete with all the right functionality!
