Hello,
I´m looking at the documentation for a Checkout UI extension date picker.
Would it be possible to add support for a list of enabled dates? I´m about to do an extension where all dates should be disabled besides a some customer specific dates.
It would be nice if I could provide the component with the list of enabled dates which I have, instead of having to calculate the opposite dates and disable those.
Hey @Maja_Novicell 
- thanks for reaching out. In the latest release (2025-10), we do include an allow feature which enables the ability to block off certain dates that I think should work here for you:
This does mean migrating to our Preact/Web Comoponents version of Polaris/Checkout UI Extensions, so it would need a bit of work if you’re using an existing extension app, but this would be the method we’d recommend. Hope this helps!
