This feature is requesting a Blazor version of the RadPropertyGrid, or a more modern Material Design(ish) equivalent.
As more customers are adopting Blazor, we're porting our rich design time tooling to the web in SaaS type offers. No Blazor control vendor has this type of control today, and it's sorely needed. Even finding a Web/Angular version of this type of control is practically impossible.
Having this control combined with the existing Telerik Blazor property editors (combo boxes, edit fields, boolean controls, color pickers, font pickers, etc.) would give you a strong leg up on your competitors.
Note: Our company is already licensing your Blazor controls and I speak to Maria every few months on the roadmap.
