I want to build the function drag/drop using CDK show grid layout like this demo: https://tiberiuzuld.github.io/angular-gridster2/
But can't do that. I can only do it like this demo https://angular-dragdrop-grid-dj41ya.stackblitz.io and https://angular-6dq2i1.stackblitz.io
NOTE: I don't want to use the gridster library. It just needs to use CDK in angular like what I did in the example above.
Hope everyone can help me. Thank so much
