# Show or hide checklist on URL changes

If your checklist is shown (or hidden) based on which URL the user is on, and your app is a Single Web Application (most of the SaaS websites are), you need to call `window.Alvis("page")` whenever the URL or route changes.

```javascript
window.Alvis("page");
```
