title: Selenium Wait for anyone of Element to visible
body: <p>While Clicking a particular button - my test site will open modal window. </p>
  
  <p>But the modal window opens are differ, either it opened with <code>modal window 1 or modal window 2</code> </p>
  
  <p>Both are having different title, different options and different locators. 
  Now I should have to wait until the modal <code>window open Either 1 or 2</code>. </p>
  
  <p>Is it possible to wait until either one modal window (WebElement) is visible? </p>
  
  <p>I have searched in WebDriverWait methods, but all methods are to wait until a particular WebElement to visible or clickable. </p>
  
  <p>I can't find a better method to wait until either one is visible. </p>
  
  <p>Could you suggests any one method to solve this situation?</p>
