HubSpot Forms in React: Solving Multi-Tab Issues for a Seamless Storefront Experience

Alright, fellow HubSpot users, RevOps pros, and e-commerce marketers! Let's chat about a real-world development head-scratcher that recently popped up in the HubSpot Community. It's the kind of issue that can really trip up your custom storefronts and integrations, especially when you're striving for a truly seamless, Shopify like experience in HubSpot.

The discussion revolved around a developer trying to integrate HubSpot forms into a React application using hbspt.forms.create. Sounds straightforward enough, right? But here's where it got tricky: the form would load perfectly fine in the first browser tab. Open a second tab to a different page with another HubSpot form, and boom – issues. The form wouldn't render correctly, leading to a broken user experience.

The Multi-Tab Mystery: What Went Wrong?

The original poster, grappling with this problem, shared screenshots illustrating the error:

This isn't just a minor glitch; for any e-commerce site or lead generation page, a non-functional form is a conversion killer. Imagine a customer trying to sign up for a newsletter or request a demo, only to be met with a blank space or an error. Not ideal, especially when you're building a robust customer journey.

Community Experts Weigh In

A community moderator initially jumped in, offering some general resources on HubSpot forms, including specific documentation for HubSpot forms, Forms reference, and Legacy forms. While useful for background, the real detective work began when an experienced community member joined the discussion.

This expert asked some crucial clarifying questions:

• Is this a 'legacy' form?
• Is the form you wish to render the same on each page of your app?
• Is the form constructed in 'raw' mode?

These questions cut straight to the heart of the issue. The expert mentioned their own experience using customized form scripts in tabbed contexts successfully, hinting that proper JavaScript construction is key. They also pointed directly to the legacy forms documentation, noting a desire for updated guidance on newer form setups.

The 'Aha!' Moment: Legacy Forms and Raw HTML

The original poster confirmed that it was indeed a legacy form. But here was the critical detail: the 'Set as raw HTML form' setting was turned off. They questioned if this could be the root cause.

And bingo! The expert's follow-up confirmed this suspicion: "All I can say is that many form customization approaches tend to rely on the form NOT being rendered in an iframe i.e. raw. Your mileage may vary."

This is a significant insight for anyone integrating HubSpot forms into a custom application, especially a React app. When the 'Set as raw HTML form' option is turned off, HubSpot typically renders the form within an iframe. While this works well for standard implementations, iframes can introduce complexities and limitations in single-page applications (SPAs) like those built with React, or when multiple instances are attempted across tabs.

The issues could stem from:

• Scoped JavaScript: Iframes create an isolated browsing context. Scripts within one iframe generally can't directly interact with content or scripts in another iframe or the parent page, leading to potential conflicts or failed initiations when multiple forms try to load.
• Resource Loading: The way HubSpot's form scripts are initialized might not be designed to handle multiple iframe-based loads across different tabs of the same React application simultaneously without conflicts.
• React's Lifecycle: React manages its DOM differently. Injecting iframes dynamically and expecting them to re-initialize external scripts reliably across various component lifecycles and tab changes can be problematic.

Actionable Takeaways for Your HubSpot Integrations

If you're encountering similar issues with HubSpot forms in your React (or any SPA) environment, here's what you should consider:

1. Identify Your Form Type: First, check if you're using a legacy HubSpot form. While HubSpot is moving towards newer form experiences, many older forms still exist and are in use.
2. Enable 'Raw HTML Form' Setting: For custom integrations, particularly in React apps, it's often best practice to enable the 'Set as raw HTML form' option. This prevents the form from rendering in an iframe, giving your application more direct control over its DOM and script execution.
3. Review Your Integration Logic: Ensure your React component properly handles the lifecycle of the hbspt.forms.create function. You might need to ensure forms are properly unmounted and remounted or that the HubSpot script is only loaded once globally if possible, or managed carefully for each form instance.
4. Test Thoroughly: Always test your forms across multiple tabs, different browsers, and various user flows to catch these edge cases before they impact your live site.

ESHOPMAN Team Comment

This community discussion highlights a crucial point for anyone building custom e-commerce experiences with HubSpot. Relying on iframe-based form rendering for modern React applications is often a recipe for integration headaches. For a truly robust and seamless customer journey, especially when aiming for a Shopify like experience in HubSpot, developers need granular control. Enabling raw HTML forms is usually the superior approach, allowing for cleaner integration and avoiding the multi-tab conflicts seen here. It's a testament to the power of the HubSpot platform, but also a reminder that some of its older features require thoughtful implementation in contemporary web environments.

Solving these kinds of technical challenges is vital for maintaining a smooth user experience, ensuring your lead capture and checkout processes are flawless. The HubSpot Community continues to be an invaluable resource for navigating these nuances, proving that collective expertise can unblock even the trickiest development hurdles. Keep building, keep integrating, and keep those forms converting!
