How can I prevent scroll when my nav is open in Webflow using code? The scroll is disabled correctly when I change the class name of the second 'menu', but it does not get activated when the menu is closed. It doesn't work at all if both class names are the same. Can anyone provide assistance with this issue?

To prevent scroll when your nav is open in Webflow, you can achieve this by adding custom code to your project. Here's a step-by-step guide to help you implement it correctly:

1. Open your Webflow project and navigate to the page where you want to prevent scrolling when the nav is open.

2. Add a custom attribute to the body element of your page. To do this, select the body element in the Webflow Designer, go to the Settings panel on the right-hand side, and click on the "Custom Attributes" tab.

3. Add a new custom attribute with the name attribute set to "scroll-disabled". This attribute will be used to determine if scrolling should be enabled or disabled.

4. Now, you need to add some custom code to handle scrolling. Go to the Project Settings in the Webflow Designer (click on the gear icon in the left-hand sidebar) and select the "Custom Code" tab.

5. In the "Head Code" section, add the following code snippet:

```javascript

```

6. Next, you'll need to add some interaction to your nav element to toggle the scroll-disabled attribute. Select your nav element in the Webflow Designer.

7. In the Interactions panel, create a new interaction for opening the nav. In the "Affect different element" section, choose the body element.

8. Now, add an action to the interaction that modifies the scroll-disabled attribute of the body element. Choose the "Set Attribute" action and set the attribute to "scroll-disabled".

9. Select the nav close button or any element that closes the nav, and create a new interaction for closing the nav.

10. Add an action to the interaction that removes the scroll-disabled attribute from the body element. Choose the "Remove Attribute" action and set the attribute to "scroll-disabled".

11. Publish your Webflow project to see the changes live.

With these steps, you should be able to prevent scrolling when your nav is open in Webflow. The custom code checks for the presence of the scroll-disabled attribute on the body element and disables scrolling when the attribute is present. When the nav is closed, the scroll-disabled attribute is removed, enabling scrolling again.
