Answer 1

Please Try in this way

var ul = driver.findelement(By.XPath("//ul[contains(@class,'your class name')]")).ToList();//loop over here. or if you know index than use it directly.
                var Select = ul[your index].FindElements(By.TagName("li")).ToList();
                foreach (IWebElement item in Select)
                {
                    if (item.Text.Trim() == "Your Text")
                    {
                        DateTime start = DateTime.Now;
                        while ((DateTime.Now - start).TotalMilliseconds < 1500)
                        {
                             Application.DoEvents();
                             System.Threading.Thread.Yield();
                        }
                        item.Click();
                        break;
                    }
                }

i hope it will help you.

Answer 2

Try this one when you open your dropdown.

  Driver.FindElements(By.CssSelector(".col-xs-3")).First(e => e.Text = "TE_GL1").Click();

Or just click first element

  Driver.FindElements(By.CssSelector(".col-xs-3")).First().Click();

As it turns out Thread.Sleep(5000); worked!
