Description

The ASP.NET Core TileLayout supports the option to dynamically add and remove items.

This demo demonstrates a dashboard with a sidebar where the sidebar items can be dragged and dropped to the left TileLayout. Items from the latter can be removed as well by clicking on the close button.
