How can I set a default option for the select dropdown button in Webflow e-commerce using basic JavaScript lines?

To set a default option for a select dropdown in Webflow e-commerce using basic JavaScript, you can inject a small script to select the desired option on page load.

1. Identify the Select Element

• Add a unique class to your select dropdown if you haven’t already (e.g., variant-select, size-dropdown, etc.).
• You can find this class under the Element Settings Panel in Webflow.

2. Add Custom Code via Page Settings or Embed

• Go to your Page Settings or use a Custom Code Embed element on the page.
• Place your JavaScript just before the closing </body> tag if using Page Settings.

Example basic script:

<script>  document.addEventListener("DOMContentLoaded", function () {    const dropdown = document.querySelector('.your-class-name');    if (dropdown) {      dropdown.value = "YourOptionValue";      // Trigger change event if needed      dropdown.dispatchEvent(new Event('change'));    }  });</script>

Key Points

• Replace .your-class-name with the actual class you assigned to the <select> element.
• Replace "YourOptionValue" with the value of the <option> you want to select by default. This must match exactly.
• Use dropdown.dispatchEvent(new Event('change')) to simulate a user interaction so Webflow’s bindings (e.g., e-commerce variant switching) are properly triggered.

3. Save and Publish

• Save your changes and publish the site to test the live behavior.
• Confirm that the desired option is selected when the page loads.

Summary

To set a default option for a select dropdown in Webflow e-commerce, use JavaScript targeting the dropdown's class and set its .value. Be sure to trigger a change event so Webflow recognizes the default selection properly.
