UIXV2 Sandbox iframe attributes

We'll update the developer documentation soon, but here's a quick example.

Application definitions (appdef.xml) may include a new attribute, e.g.:

<dashboard id="abc" sandbox-attributes="allow-popups allow-downloads">…</dashboard>
<module environment="shellui" sandbox-attributes="allow-downloads allow-popups">...</module>

Afterwards, you should be able to see the attributes in the M-Files Admin tool after the application has been installed:

Which version of m-files is it? I just updated to the new 25.9... and I can't see the attributes in applications, and even though I added the attributes to the definition as described, it's not working.

The sandbox attributes are supported with the October release (25.10), generally available next week. You can find this enhancement on the release notes with ID CE-706.

Is it possible to get an early access version?

Yes, it's available for M-Files partners in the Partner Group. Refer to these Partner Portal instructions: Community Partner Group - How to join

Unfortunately, we cannot find it on the partner portal. Do you have a direct link?
