- 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.
Using Livewire to create dynamic forms is a powerful way to improve user experience by updating form fields in real-time based on user input. This tutorial demonstrated how to set up a dynamic dropdown menu in Laravel using Livewire, but the principles can be applied to any form field.
