How can we select an option from a combo box in Selenium

Answer 1

If the options are under the htmal tag <select> then we can use select method to select the options

Ex: 1st fine the main element under which option are present

element = driver.findElement(By.name("files"));

and then use Select class with theirs methods selectByIndex() to select 

Select select = new Select(element);

select.selectByIndex(3);
