Event Handling Development Tutorials, Guides & Insights

You can change the inner content of an element using the innerHTML or textContent properties.

const element = document.getElementById('myElement');
element.innerHTML = '<strong>Hello, World!</strong>'; // Sets HTML content
element.textContent = 'Hello, World!'; // Sets plain text content

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.
