Pulling all dropdown elements with selenium

The problem was largely solved by Ali Imran Ansari. I express my special thanks for what it contains. However, there is only one problem: the first line lists all dropdown elements on a single line. How can we prevent this? Please take a look at the picture to understand what I mean.

These are Ali Imran Ansar's codes

IList selectElements = drv.FindElements(By.Id("ddlDersler"));
// Create DataTable outside the loop to avoid resetting it in each iteration
DataTable dt = new DataTable();
foreach (IWebElement select in selectElements)
{
    var selectElement = new SelectElement(select);

    //// Create a new column for each dropdown
    DataColumn dtcol = new DataColumn(select.Text);
    dt.Columns.Add(dtcol);

    // Create a new row for each option in the dropdown   // her satira dropdown çeken yer burasi
    foreach (IWebElement option in selectElement.Options)
    {
        DataRow row = dt.NewRow();
        row[select.Text] = option.Text.Trim();
        dt.Rows.Add(row);
    }
}
// Set the DataTable as the DataSource after the loop
dataGridView1.DataSource = dt;

First of all, thank you very much for your interest. However, these codes give the same results as I got before. Instead of listing the courses one by one, it only gives the number of dropdown elements.

Please try to follow this basic example and try: -

using OpenQA.Selenium;
using OpenQA.Selenium.Chrome;
using System;
using System.Collections.Generic;
using System.Windows.Forms;

class Program
{
    static void Main()
    {
        // Initialize the WebDriver (assuming Chrome in this example)
        IWebDriver driver = new ChromeDriver();

        // Navigate to the webpage with the dropdown menu
        driver.Navigate().GoToUrl("your_website_url_here");

        // Locate the dropdown element (replace "your_dropdown_id" with the actual ID or other locator)
        IWebElement dropdown = driver.FindElement(By.Id("your_dropdown_id"));

        // Get all options from the dropdown
        List options = new List(dropdown.FindElements(By.TagName("option")));

        // Create a DataGridView
        DataGridView dataGridView = new DataGridView();
        dataGridView.Columns.Add("ColumnHeader", "ColumnHeader");

        // Iterate through options and populate DataGridView
        foreach (IWebElement option in options)
        {
            string optionText = option.Text;

            // Add the option text to the DataGridView
            dataGridView.Rows.Add(optionText);
        }

        // Display the populated DataGridView (you might want to add this to a form or handle it according to your application)
        MessageBox.Show("Dropdown options retrieved and added to DataGridView!");

        // Close the browser
        driver.Quit();
    }
}
