To defer parsing of external JavaScript in Webflow until the tab bar parent is clicked, you can follow the steps below:

  1. Open your Webflow project and go to the page where you have the tab bar parent element.

  2. Select the tab bar parent element, and in the Interactions panel, create a new click trigger for the parent element. This will allow you to execute JavaScript code when the tab bar parent is clicked.

  3. Open the Custom Code settings for your Webflow project. You can do this by clicking on the gear icon in the Designer and selecting "Custom Code" from the dropdown menu.

  4. In the <head> section of the Custom Code settings, add the following script tag:

    ```html

    ```

    Replace 'https://example.com/path/to/external/script.js' with the actual URL of your external JavaScript file.

  5. Go back to the Interactions panel and edit the click trigger for the tab bar parent.

  6. In the Actions section of the click trigger, select the "Run JavaScript" action.

  7. In the JavaScript code field for the action, enter the following code:

    ```javascript
    loadExternalScript();
    ```

  8. Save your changes and publish your Webflow project.

Now, when the tab bar parent is clicked, the external JavaScript file will be dynamically loaded into the page. This ensures that the JavaScript is not parsed and executed until it is actually needed, improving the initial loading performance of your website.
