Persistent Loading Errors and Layout Discrepancies Across Multiple Browsers While Integrating a Dynamic Food Menu into Our Scheduling Workflow

I’ve been working on a website that hosts a dynamic restaurant menu, which is intended to sync seamlessly with our online scheduling and booking system. Recently, I’ve noticed intermittent loading errors when users try to view the menu on different devices and browsers, especially when transitioning between mobile and desktop views. Elements of the menu occasionally fail to render properly, causing buttons to overlap and certain sections to disappear entirely. This is particularly problematic because the menu is also supposed to feed into our scheduling system, allowing users to select items while booking their slots, but any disruption in rendering leads to incomplete booking flows. I’ve attempted basic troubleshooting like clearing caches, disabling extensions, and testing across multiple browsers, yet the problem persists and appears to be tied to the way dynamic content is loaded and integrated with the scheduling platform.

Another concern I’ve noticed involves slow performance when users interact with the menu in real time. For instance, filtering categories or searching for specific items often triggers delays, sometimes up to several seconds, which in turn affects the responsiveness of the scheduling interface. From a technical standpoint, the menu uses client-side JavaScript to fetch and display content asynchronously, but I suspect there might be conflicts with the embedded scheduling widgets or third-party scripts. While the rest of the website performs well, the sections tied to menu rendering show unusual CPU spikes and occasional network timeouts, which could be causing the erratic behavior. I am looking for advice on how to diagnose whether these slowdowns are caused by script conflicts, inefficient rendering, or server-side throttling.

Finally, I am concerned about the long-term maintainability of the system. The menu is updated frequently, and every update requires testing its integration with the scheduling system to ensure nothing breaks. Ideally, I would like to implement a more robust solution that automatically synchronizes updates without introducing layout or performance issues. I’m also exploring whether optimizing asset loading, lazy-loading menu items, or restructuring the JavaScript modules could mitigate these problems. If anyone has faced similar issues while embedding dynamic content into scheduling tools or has best practices for ensuring smooth interaction between a frequently updated menu and booking widgets I would greatly appreciate detailed insights or suggestions. Please assist as I am not a techie

Hey ​@Kimpollard -

Are you able to share a link to the site you are working on? If so, I can look into the issue further to determine if it is Calendly’s embed code that is causing the issues above (and potential solutions to the issue).

This sounds like a common issue with dynamic JavaScript content conflicting with third-party widgets and responsive breakpoints. A good starting point is to isolate the menu and scheduling scripts, check for console errors, and defer or lazy-load non-critical assets to reduce rendering conflicts and CPU spikes. In the long term, separating the menu into a well-structured API-driven module and syncing it with the booking system server-side can greatly improve stability and maintainability.

I’ll start by isolating the menu and scheduling scripts and reviewing console errors more closely, especially around breakpoint changes and initial load. Deferring non-critical assets and moving toward a cleaner, API-driven menu module that syncs server-side with the booking flow also sounds like the right long-term direction for stability.

One quick question: have you seen cases where embedding the scheduling widget inside a dynamically re-rendered container (for example, when the menu filters or layout change) causes the widget to partially break or reinitialize? If so, is the recommended approach to keep the scheduling widget in a static container and only pass data to it, rather than re-rendering it along with the menu?
