How to Handle Dropdown in Table in Selenium?

Published in Web Automation 3 mins read

To interact with dropdowns within a table using Selenium, you need to locate the dropdown element and then manipulate it using the appropriate methods. Here's a step-by-step guide:

1. Locate the Dropdown Element:

  • Identify the Dropdown: Use Selenium locators like id, name, xpath, or cssSelector to find the dropdown element within the table.
  • Inspect the Element: Use your browser's developer tools to inspect the dropdown element and find its unique attributes.
  • Example:
    • Using XPath: //table[@id='myTable']//tr[2]/td[3]/select (locates the dropdown in the second row, third column of a table with the id 'myTable')
    • Using CSS Selector: #myTable tr:nth-child(2) td:nth-child(3) select (achieves the same as the XPath example)

2. Select an Option from the Dropdown:

  • Create a Select Object: Use the Select class from Selenium to interact with the dropdown.

  • Select by Value: Use select_by_value() to select an option based on its value attribute.

  • Select by Visible Text: Use select_by_visible_text() to select an option based on the text displayed in the dropdown.

  • Select by Index: Use select_by_index() to select an option based on its position in the list (starting from 0).

  • Example:

    from selenium.webdriver.support.ui import Select

# Find the dropdown element
dropdown = Select(driver.find_element(By.XPATH, "//table[@id='myTable']//tr[2]/td[3]/select"))

# Select an option by value
dropdown.select_by_value("option_value")

# Select an option by visible text
dropdown.select_by_visible_text("Option Text")

# Select an option by index
dropdown.select_by_index(1)

3. Handle Multiple Select Dropdowns:

  • Check for Multiple Select: Use the is_multiple() method to determine if the dropdown allows multiple selections.
  • Select Multiple Options: If the dropdown is a multiple select, use select_by_value(), select_by_visible_text(), or select_by_index() to select multiple options.
  • Deselect Options: Use deselect_by_value(), deselect_by_visible_text(), or deselect_by_index() to deselect previously selected options.

4. Handle Dynamic Dropdowns:

  • Wait for Element Visibility: Use explicit waits to ensure the dropdown element is fully loaded and visible before interacting with it.
  • Handle AJAX Requests: If the dropdown content is loaded dynamically using AJAX, use explicit waits or web driver waits to ensure the options are available before selecting.

By understanding these steps and utilizing the appropriate Selenium methods, you can efficiently handle dropdowns within tables in your automation scripts.
