using selenium with a dropdown menu

it depends what kind of dropdown
There are 2 dropdowns 
1- HTML
2- SELECT

we determine what kind of dropdown it is
 -By tagName.We inspect.If it has <select> tag, it means it is <select> dropdown. 
 -If it is HTML, we can locate and click just as any other web element.
 
 I handle Select type of dropdown by using Select class from Selenium. 
    - Methods to select from dropdown:
        - selectByVisibleText
        - selectByValue
        - selectByIndex 
        
I verify which option is selected in a dropdown?
 - If we want to get the currently selected option, 
 we use getFirstSelectedOption() method.
        -> return type: currently selected option as a web element
        
       
--> .getOptions();
    -> This method will return all of the options in the <select> web element.
    -> return type: List<WebElement>
        

driver.findElement(By.id("dropdownlistone")).click(); // To click on drop down list
driver.findElement(By.linkText("india")).click(); // To select a data from the drop down list
