Currently external user can become provisional member based on permission granted by the owner of sheet. This access granting should be controlled by System Admin based on an approval process. Otherwise it'll be very difficult for System Admin to monitor the seatings as well as providing inconvenience to users when needing to downgrade their seats.

Proposed idea:

1. Owners can only assign external user as Viewer or Guest.
2. System Admin to control if external user can setup as provisional member

Hi Smartsheet Team,

I wanted to reach out with some feedback and a request regarding how Smartsheet forms are embedded on websites. I've been long-time user and fan of Smartsheet since 2008, and the form system has been a big part of how we collect and manage submissions for various clients and internal workflows.

What's changed:

Up until recently, we had been using a server-side method to pull form content directly into our sites. It allowed us to control layout and responsiveness, and provided a smooth, native experience for users on all devices.

After a recent update to the way your forms are rendered, that approach no longer works. We've since had to move to the standard iframe embed method — and unfortunately, that’s introduced some real usability issues we can’t solve from our side.

The issue with iframe embedding:

• The height can’t adapt to the form content. Since the forms live on a different domain, we can’t access the DOM inside the iframe to detect or adjust height. This forces us to guess how tall the form is.
• Conditional fields break layouts. Many of your forms use conditional logic, meaning the form grows as users select options. If the iframe height doesn’t adjust, content gets cut off — and users are stuck scrolling inside the iframe, which is especially rough on mobile.
• Responsiveness is limited. There’s no good way to make the iframe “smart.” We’ve tried everything from viewport-based sizing to step-based height guesses, and nothing provides the clean, scroll-free experience users expect.

What would help:

Other platforms we work with — like Calendly, Typeform, and JotForm — handle this much better. Here are some options they offer:

• postMessage support: Their forms send the height of the form to the parent window using JavaScript (postMessage). This lets us resize the iframe on the fly.
• JavaScript embed scripts: Some provide a small JS file we include on our site that handles embedding, resizing, and mobile behavior — no iframe guessing required.
• Resize events or observer hooks: Others give us access to events that fire when the form size changes, so we can respond accordingly.

Even a simple postMessage implementation from your side (e.g. on form load or when new fields appear) would make a massive difference. Something like this is all that’s needed:

jsCopyEditwindow.parent.postMessage({ height: document.body.scrollHeight }, '*');

Final thoughts:

Smartsheet continues to be a great tool for us — this is just one of those areas where a small change on your side could solve a lot of downstream issues. We know you’re likely balancing a lot of feature requests, but we’d really appreciate if this could be passed along to the product team.

Happy to help test or provide more detail if needed. Thanks again for your time and for all the work that goes into the platform.

I'm not sure why this feature even exists if it can't be used on Reports. 99.9% of my users see ONLY various reports — they don't get to see the underlying sheet, so the column descriptions, only available on the underlying sheet, is pretty useless.
