To perform mouse hover function over a main menu which has sub elements, for this we have to chain all the actions that we want to achieve in one go.

• In order to perform it, first move on to the main menu element which has sub elements and click on the new option.

• To achieve mouse hover action we use 'Action' API constructor with 'moveToElement' method;

Steps:

1. Launch the site URL(findnerd.com/NerdDigest/)

2. Mouse hover over a main menu(nerd digest)

3. Now find out the hidden element which will only  be visible on mouse hover

4. Click on new option or sub menu item(.net)

Sample code:-

import java.util.concurrent.TimeUnit;
 
       import org.openqa.selenium.*;
 
       import org.openqa.selenium.interactions.Actions;

 
	public class mouseHoverAction{

 
   	public static void main(String[] args) {
 
        driver = new FirefoxDriver();
 
        driver.manage().timeouts().implicitlyWait(10, TimeUnit.SECONDS);
 
        driver.get("findnerd.com/NerdDigest/");
 
        WebElement mainmenu = driver.findElement(By.xPath(".//*[@id='offshoreindialive']/div[9]/ul/li[10]/a"));
 
        Actions action = new Actions(driver);
 
        action.moveToElement(mainmenu).build().perform();
 
        driver.findElement(By.xpath(".//*[@id='offshoreindialive']/div[9]/ul/li[5]/ul/li[2]/ul/li[1]/a")).click();
 
        }
 
}
