How can I create a dropdown menu in the hero section of a Webflow website that is preselected based on the ad that brought the user there?

To create a dropdown menu in the hero section of your Webflow website that is preselected based on the ad that directed the user to your page, you need to use URL parameters to identify the source and customize the dropdown selection accordingly.

​

1. Add a Dropdown Menu in Webflow

• Go to the Designer and drag a Dropdown component into the hero section of your webpage.
• Set up the Dropdown options that you want to display.

​

2. Get the URL Parameters

• When setting up your ads, ensure that they append a unique query parameter to the URL (e.g., ?ad=option1).

​

3. Use JavaScript to Preselect Dropdown Based on URL

• You will need a small JavaScript snippet added to your site to read the URL parameter and set the corresponding dropdown option.
• Add the following snippet to the Page Settings under Custom Code > Footer Code:

​

  ```javascript

  <script>

    document.addEventListener('DOMContentLoaded', function() {

      const urlParams = new URLSearchParams(window.location.search);

      const adParam = urlParams.get('ad');

      if (adParam) {

        const dropdown = document.querySelector('.w-dropdown');

        const options = dropdown.querySelectorAll('.w-dropdown-item');

        options.forEach(option => {

          if (option.textContent.trim() === adParam) {

            dropdown.value = adParam;

          }

        });

      }

    });

  </script>

  ```

​

4. Publish and Test the Setting

• Publish your site and test the dropdown by navigating to different URLs with query parameters like ?ad=option1.
• Ensure that the correct option is automatically selected based on the URL parameter.

​

Summary

By following these steps, you can make the dropdown menu in your hero section preselect an option based on the ad parameters appended in the URL, thus personalizing user experience based on entry sources.
