NoSuchElementException on performing Mousehover action in selenium - selenium

Question

I have a webpage in which I am trying to perform a mouse hover.. There is an element named "Entity Records" on which if you hover your mouse it displays a menu. In that menu I need to click on an element named Create New record.
I have tried 3 different set of codes but it's not working for me..
1st One:
WebElement el = driver.findElement(By.xpath("\\...."));
action.moveToElement(el).build().perform();
Actions builder = new Actions(driver);
builder.moveToElement(driver.findElement(By.cssSelector("..."))).click().build().perform();
2nd one:
WebElement entityrecordsmenu = driver.findElement(By.cssSelector("..."));
Actions builder = new Actions(driver);
builder.moveToElement(entityrecordsmenu).build().perform();
WebElement createnewrecord = driver.findElement(By.cssSelector("..."));
createnewrecord.click();
3rd one:
Actions action2 = new Actions(driver);
WebElement ele = driver.findElement(By.xpath("...));
action2.moveToElement(ele).build().perform();
Actions build2 = new Actions(driver);
build2.moveToElement(driver.findElement(By.xpath("..."))).click().build().perform();
1st and 2nd code are doing the mouse hover fine, but its not clicking on the menu element. Can anyone suggest me the correct way of doing this?

Answer 1

After mouse hover, try by giving some wait to get that element displayed and then click.
WebElement entityrecordsmenu = driver.findElement(By.cssSelector("..."));
Actions builder = new Actions(driver);
builder.moveToElement(entityrecordsmenu).build().perform();
//provide wait here to display dropdown
driver.manage().timeouts().implicitlyWait(10, TimeUnit.SECONDS);
//some time implicity wait may fails then use thread.sleep
//Thread.sleep(3000);
WebElement createnewrecord = driver.findElement(By.cssSelector("..."));
createnewrecord.click();
//if still above once does not work you can try
Actions builder1 = new Actions(driver);
builder1.moveToElement(entityrecordsmenu).click(driver.findElement(By.cssSelector("..."))).build().perform();
