Selenium Webdriver - click on hidden elements

Question

I am trying to automate upload file functionality in Google Drive.

The element used to pass parameters is hidden with height - 0px.

None of the user actions

Answer 1

Try this:

WebElement elem = yourWebDriverInstance.findElement(
   By.cssSelector(".uploadmenu > input"));
String js = 
  "arguments[0].style.height='auto'; arguments[0].style.visibility='visible';";
((JavascriptExecutor) yourWebDriverInstance).executeScript(js, elem);

Here I have replaced XPath by CSS Selector. Let me know Is the above scripting is working or not.
