I am working on a regression suite for a complex e-commerce site and need to select an item from a hidden sub-menu. The sub-menu only appears when hovering over the parent category. I’ve tried basic click methods, but they fail because the element isn't visible. What is the standard approach using the Actions class to perform a move-to-element sequence reliably across different browsers?

The industry standard for this in Selenium is using the Actions class. You first need to instantiate the Actions object with your driver, then use the moveToElement() method on the parent menu. It is crucial to follow this with a perform() call to actually execute the hover. Once the hover is active, the DOM updates, and you can then find the sub-menu link and click it. I recommend adding a short WebDriverWait with ExpectedConditions.visibilityOfElementLocated for the sub-menu item to ensure the animation has finished before the script attempts to click, otherwise, you might run into an ElementNotInteractableException.
Are you experiencing issues where the hover works in Chrome but fails in Firefox or Safari due to differing browser driver behaviors, or is the sub-menu disappearing too quickly for the script to catch it?
You can simplify this by using Actions action = new Actions(driver); action.moveToElement(menu).moveToElement(subMenu).click().build().perform(); to chain the movements.
I agree with Nancy! Chaining the actions in a single build and perform sequence is a very clean way to write readable code in a software development environment while handling multi-level navigation.
Richard, that is exactly my problem. In Chrome, the hover is stable, but in Firefox, the menu flickers and disappears before the click. Do you think using a pause() within the Action chain or perhaps moving the mouse to a specific offset on the parent element would help stabilize the interaction across different browsers, or should I look into a JavaScript executor workaround to force the menu to stay visible?
