问题
I'm playing with cdk Drag and Drop cause I need it to create a POC for work. I started with this code from the documentation website. I saw that every time I drag an element outside its list, said element is hidden until I drop it in the same list or in another one.
So tell me if I'm wrong, but it seems that the dragged element is not a copy of the list item, but instead it's the element itself.
In conclusion I want the list to not change its layout while I'm dragging one of its elements.
Long story short:
CURRENT BEHAVIOUR
EXPECTED BEHAVIOR
I didn't found anything to do this in the cdk documentation.

In your stackblitz change in cdk-drag-drop-connected-sorting-example.css
change
.cdk-drag-placeholder {
opacity: 0;
}
into: (or just remove it)
.cdk-drag-placeholder {
/* opacity: 0; */
}
the fact its disappearing is due to css styling of the placeholder.
If you want to disable Sorting. Have a look HERE!
