Hi,in CMS 11 and Commerce 13, is it possible to extend the order search form in the new CSR UI with more columns?
In Commerce 13, we support CSR extensibility. Here's the developer guideline: https://github.com/episerver/Quicksilver/tree/master/Sources/EPiServer.Reference.Commerce.Site/CSRExtensibility/react-app
(this doc is included in Quicksilver, our sample site, which is no longer supported for now but the doc is still valid)
There are some fixed position that support extensibility: the header and footer of the order listing page, the tab in order detail and contact detail...
For the columns of order search form, it is not currently supported for extensibility. I've transferred this feature request to the product team, so they can investigate and consider adding in the next versions.
