angular drag and drop cdk. I want to know, how to get the index value of all items in the drag and drop on event cdkDropListDropped.

Or is there any event, which I can rely on. I want to know the index value of all items in the list once the item in the list of moved to new location.

What for? You get the previous and current index in the drop event. Once you use moveItemInArray you have the final array and as a result you also know all indices.

@Airblader is correct. Once you know the previous and current index in the drag event, you can move the item into its new position in the array.

[digish777]

I get the index of the moved element alone. not all the items in the dropped div. I want all updated indexes of the items in the dropped div.

[crisbeto]

Wouldn't the indexes of all items just be between 0 and the length of the items in the list?

[digish777]

I want the exact indexes of the all the items in the list after moving. I need the update another list where I maintain the indexes of all items in the list. is there any way to do that?. Once I move an item. I need updated indexes or positional index of all items in the dropped container.

[Airblader]

You use moveItemInArray (provided by CDK) to update the array of your items (or a copy of it if you prefer). Now you have an array that reflects the exact order of all items, so the indices of items within this array are all updated.
