Getting Started
▼
This widget is initially expanded. Click the header to collapse it. Each widget can be independently controlled by clicking its header. The state is managed through the 'expanded' class on the widget container, which triggers CSS transitions for smooth animations.
Implementation Details
▼
The widget uses a simple JavaScript function that toggles the 'expanded' class on the widget element. The CSS handles the visual transitions using max-height with overflow hidden. This approach provides smooth animations without requiring complex JavaScript libraries or frameworks.
