+## Debug
+
+Sometimes when you click the dropdown and it opens, you may not be able to inspect styles because the menu closes as soon as you move the mouse.
+
+To work around this, paste the click code below into the browser console. After triggering it, select the related HTML element from the Elements panel and debug the styles normally.
+
+```js
+document.getElementsByClassName('choices')[0].click();
+```
