If you're facing the issue where a modal in a Webflow CMS collection only overlays the Collection List Wrapper area instead of the entire viewport, there are a few steps you can take to fix it:
1. Check the positioning of the modal element: Make sure that the modal element is set to have a position of "Absolute" or "Fixed". This allows it to be positioned relative to the viewport instead of other elements on the page.
2. Adjust the z-index: Verify that the modal element has a higher z-index value than the Collection List Wrapper. The z-index determines the stacking order of elements, with higher values appearing on top. You can set the z-index value of the modal to a high number (e.g., 9999) to ensure it overlays all other elements.
3. Set the width and height to 100%: Ensure that the modal element has a width and height value of 100%. This ensures that it takes up the entire width and height of the viewport.
4. Verify the modal's parent container: Double-check that the modal element is positioned correctly within its parent container. If the parent container has a specific width or height defined, it can restrict the modal's overlay to that area only. Make sure the parent container is set to 100% width and height as well if necessary.
5. Review any conflicting styles: Look for any conflicting styles that may be affecting the modal's positioning or overlay behavior. Check for other elements or classes that might interfere with the modal's CSS properties.
6. Debug using the browser's dev tools: Inspect the modal element using your browser's developer tools. This will allow you to see if any CSS properties, such as position or z-index, are being overridden by other styles. You can also test changes to the CSS in real-time using the dev tools to see if they fix the issue.
By following these steps, you should be able to fix the issue where the modal in your Webflow CMS collection only overlays the Collection List Wrapper area instead of the entire viewport.
