You can click the drop down and wait for the options to get displayed and then you can click the option from it.
您可以单击下拉菜单并等待显示选项，然后您可以单击其中的选项。
or
或者
Select select = new Select(driver.findElement(By.id("drop_down_id")));
select.selectByIndex(`index_value_of_option`);

Jyotsna... Your script need to wait till the field appear. For this you need to use any of the wait condition.
Jyotsna... 您的脚本需要等到该字段出现。为此，您需要使用任何等待条件。
implicit wait
隐式等待
driver.manage().timeouts().implicitlyWait(10, TimeUnit.SECONDS);
or sleep condition
或睡眠状况
Thread.sleep(2000);
or you can use Fluent wait (the best one as per my suggestion)
或者你可以使用 Fluent 等待（根据我的建议最好的一个）
public WebElement fluentWait(final By locator) {
Wait<WebDriver> wait = new FluentWait<WebDriver>(driver)
.withTimeout(30, TimeUnit.SECONDS)
.pollingEvery(5, TimeUnit.SECONDS)
.ignoring(NoSuchElementException.class);
WebElement foo = wait.until(new Function<WebDriver, WebElement>() {
public WebElement apply(WebDriver driver) {
return driver.findElement(locator);
}
});
return foo;
};
fluentWait function returns your found web element. From the documentation on fluentWait: An implementation of the Wait interface that may have its timeout and polling interval configured on the fly. Each FluentWait instance defines the maximum amount of time to wait for a condition, as well as the frequency with which to check the condition. Furthermore, the user may configure the wait to ignore specific types of exceptions whilst waiting, such as NoSuchElementExceptions when searching for an element on the page. Details you can get here
fluentWait 函数返回您找到的 Web 元素。来自 fluentWait 的文档：Wait 接口的一个实现，它可以动态配置超时和轮询间隔。每个 FluentWait 实例定义等待条件的最长时间，以及检查条件的频率。此外，用户可以配置等待以在等待时忽略特定类型的异常，例如在页面上搜索元素时的 NoSuchElementExceptions。您可以在这里获得详细信息
Usage of `fluentWait in your case be the following:
在您的情况下使用 `fluentWait 如下：
WebElement textbox = fluentWait(By.id("textbox"));

you can add wait so that the problem of late loading would be resolve.
您可以添加等待，以便解决延迟加载的问题。
driver.manage().timeouts().implicitlyWait(20,TimeUnit.SECONDS);

Thread.sleep(2000);
For selecting from drop down , there are multiple ways from which one can select :
对于从下拉菜单中选择，有多种方式可供选择：
