### Interactivity Dropdowns require `shoelace.js` for interactivity. You don’t need to initialize anything. Just include the script and everything “just works.” There is no JavaScript API. Shoelace’s philosophy believes that custom components should act like native components as much as possible. You can, however, listen for various events. - `show` – Fires when a dropdown is shown. - `hide` – Fires when a dropdown is hidden. - `select` – Fires when a dropdown menu item is selected. The second callback argument is a reference to the respective menu item. This example will log all three events for a dropdown with an id of `my-dropdown`. ```javascript $('#my-dropdown') .on('show', function(event) { console.log('show', event.target); }) .on('hide', function(event) { console.log('hide', event.target); }) .on('select', function(event, item) { console.log('select', event.target, item); // Tip: Use use event.preventDefault() to // intercept the original click event. }); ``` To show or hide a dropdown programmatically, just add or remove the `active` class to the dropdown. ```javascript // Show the dropdown $('#my-dropdown').addClass('active'); // Hide the dropdown $('#my-dropdown').removeClass('active'); ```
