How can I prevent the body from scrolling when the mobile menu overlay is active in Webflow?

To prevent the body from scrolling when the mobile menu overlay is active in Webflow, you can utilize custom code and the interactions feature. Here's a step-by-step guide:

1. Create a new interaction: Go to the Interactions panel, click on the "+" button to create a new interaction. Choose the "Menu" trigger type, and select the mobile menu trigger. For example, you might name it "Open Mobile Menu".

2. Configure the interaction: In the interaction settings, add a new action by clicking the "+" button. Choose the "Hide" action and select the mobile menu overlay element. This action will hide the overlay when the menu is closed.

3. Add custom code: Go to the Project Settings and click on the Custom Code tab. In the section labeled "Custom Code in ``", add the following CSS code:

```css
body.open-menu {
overflow: hidden;
}
```

This code will prevent the body from scrolling when the mobile menu overlay is active.

4. Modify the interaction: Go back to the interaction you created in step 1. Add a new action to be triggered when the menu closes. Choose the "Run JavaScript" action.

5. In the JavaScript field, add the following code:

```javascript
document.body.classList.remove('open-menu');
```

This code will remove the `open-menu` class from the body element when the menu is closed, allowing the body to scroll again.

6. Test and publish: Preview your site and test the mobile menu overlay. The body should no longer scroll when the overlay is active, and scrolling should be enabled again when the menu is closed.

By combining custom code and interaction settings, you can easily prevent the body from scrolling when the mobile menu overlay is active in Webflow.
