Dynamically Updating Form Fields with Livewire in Laravel

Navigate to http://your-app-url/dynamic-form in your browser. You should see a dropdown for categories. When you select a category, the subcategory dropdown should populate with the corresponding options.

  • Category Selection: The selectedCategory property is bound to the category dropdown. When a category is selected, the updatedSelectedCategory method is triggered.
  • Dynamic Subcategory Loading: The updatedSelectedCategory method calls getSubcategories to fetch the corresponding subcategories based on the selected category. The subcategories property is then updated, which dynamically updates the subcategory dropdown in the view.
  • Livewire Magic: Livewire automatically listens to the changes in the selectedCategory property and re-renders the relevant parts of the view without a full page reload.
