Draggable is a lightweight, responsive, modern drag & drop library. Draggable abstracts native browser events into a comprehensive API to create a custom drag and drop experience. For more info see
the official siteand
the Github repository.
Restricted Zones Example
- Wrap draggable zone with
.draggable-zoneand define draggable elements with.draggableand let drag & drop through.draggable-handleelement. - Add
data-kt-draggable-level="restricted"to draggable zones to set a restricted permission level to the container. - Define draggable cards with permissions levels by adding
data-kt-draggable-level="admin"to allow specific cards into the restricted container. - Restricted cards are allowed to drag into any column.
- Restricted column will only allow restricted cards
The HTML attribute is not an official attribute, and can be replaced with any other name according to your product requirements.
