Belissima Backoffice: Property Descriptions
I'm sure you're already aware of property descriptions! They’re useful to explain a property when a name doesn't give enough detail. The property descriptions have accepted markdown for a long time now (although allowed features have changed over time!). And because it’s markdown, that means we can use HTML too. And because its HTML it means we can also make use of web components, like UUI!
