What is the simplest method to separate the scrolling action of a section and its content in Webflow for the purpose of creating a two-level scrolling system, where users can navigate between sections and scroll within them?

To create a two-level scrolling system in Webflow, where users can navigate between sections and scroll within them, you can utilize a combination of Webflow's built-in features and custom interactions. Here's a step-by-step guide to achieve this:

1. Structure your layout: Create a wrapper div that will contain all the sections you want to scroll between. Inside this wrapper, add individual divs for each section. For example, you can use the "div block" element for this.

2. Set up your sections: Give each section a unique class name or ID. This will help you target them later for scrolling and interactions.

3. Enable vertical scrolling for the wrapper: Select the wrapper div, go to the Styles panel, and set the overflow property to "auto". This will enable vertical scrolling for the wrapper and separate it from the content within the sections.

4. Set the height of the sections: By default, sections in Webflow have a height setting of "auto," which means they will expand based on their content. To enable scrolling within sections, you need to manually set their height. You can do this by giving each section a specific height value using the CSS height property in the Styles panel. Alternatively, you can use the custom code option and add inline styles to each section.

5. Set up interactions: To enable navigation between sections, you can use Webflow's scroll interactions or create custom interactions using custom code. For scroll interactions, select the element (e.g., a button or link) that you want to trigger the scroll, go to the Interactions panel, and choose "Scroll" as the trigger. Configure the interaction to scroll to the desired section by selecting the corresponding class name or ID.

6. Customize scrolling within sections: To allow scrolling within each section without affecting the outer wrapper's scroll behavior, you need to disable the scroll on the wrapper while inside a section. This can be achieved using JavaScript. You can use event listeners to detect when the user is scrolling within a section and prevent the default scroll behavior of the wrapper.

Here's an example code snippet:

```
const section = document.getElementById("sectionID");

section.addEventListener("wheel", (e) => {
e.preventDefault();
section.scrollTop += e.deltaY;
});
```

Replace "sectionID" with the actual ID of the section you want to apply the scrolling to.

By implementing these steps, you can create a two-level scrolling system in Webflow where users can navigate between sections and scroll within each section independently. Remember to test and refine your design to ensure a smooth user experience.
