Selecting dropdown in WebDriverJs

Question

I have a dropdown box that I would like to select a value using WebDriverJS. I\'ve looked at the user guide below and could not find out how to do it

Answer 1

Find the select element and click on it to display the dropdown

driver.findElement(//div//select[@id="elementId"]).click();

Then select from the options and click on it. I think selecting by xpath will really work better here.

driver.findElement(By.xpath('//div//select[@id="elementId"]//option[optionIndex]')).click();
