Loading...<details> + <summary> (Click): The <details> element is a native HTML interactive widget that toggles its content open/closed when the <summary> is clicked. No CSS or JS is strictly required — it works out of the box. CSS is only used to style it and position the dropdown absolutely.:hover (Hover): A container element uses the :hover pseudo-class to reveal a hidden child element. This approach relies entirely on CSS and works on desktop. On touch devices, a tap may trigger the hover state briefly.
<details> element has excellent built-in accessibility. Screen readers announce it as an expandable widget, keyboard users can toggle it with Enter or Space, and it integrates with the browser's focus management. However, for production use, consider adding aria-label attributes and ensuring proper focus indicators for the links inside the dropdown.
<a> tags of your dropdown. Simply add the icon markup before or after the link text. The generated code is flexible enough to accommodate inline icons, and you can style them with CSS to match your design.
<details>) is recommended for most use cases. It works consistently across desktop and mobile, supports keyboard navigation natively, and doesn't cause accidental triggers. It's ideal for navigation menus, settings panels, and action menus.<details> element inside the dropdown to create a cascading submenu. For hover mode, you can nest another hover container within a dropdown item. The concept is the same: position the submenu absolutely relative to its parent item. This builder generates flat menus for simplicity, but the generated code serves as a clean foundation you can extend.
