Floating Panels in Angular Dashboard Layout component

27 Jul 2021 / 2 minutes to read

The floating functionality of the component allows you to effectively use the entire layout for the panel’s placement. If the floating functionality is enabled, the panels within the layout get floated upwards automatically to occupy the empty cells available in previous rows. This functionality can be enabled or disabled using the allowFloating property of the component.

The following sample demonstrates how to enable or disable the floating of panels in the DashboardLayout component.
