In this episode, we take a breather from the more complex stuff and focus on something simple but important—displaying child categories in our app. We start by looking at how to show the children of each category so our users can easily navigate deeper into category trees.
You'll see how to loop over the children of a category and output their titles. We also make sure each child category is a clickable link, so users can drill down right into those categories (using the child's slug in the URL). There's a quick walkthrough to show how this works with brands like Nike, and their subcategories such as NuIn, making navigation much smoother.
Finally, we check out the Laravel Debug Bar to make sure our queries are efficient and we're not accidentally running into N+1 query issues (spoiler: it's all good for now!). Consider this episode a tidy up to get category navigation working well, with a little reminder to stay mindful about performance as the app grows.
