Overview

The Re-orderable list is a very powerful control which includes several "out of the box" setups, including:

Vertical, Horizontal and Grid layouts
Vertical, Horizontal and Grid layouts using a ScrollRect

The control can be enabled in multiple flavors, featuring such capabilities as:

Allowing Dragging (allows containers that can be dropped in to but not removed)
Clone or Move child elements
Allowing dropping (containers that be dragged from but not dropped in to)

As well as events for each state of the child content as they are interacted with.

Properties

The properties of the Re-orderable List control are as follows:

Property	Description
Content layout	The container holding the child content (similar to the ScrollRect content property)
Draggable Area	Defaults to the Content Layout / parent rect transform, but can be overridden to identify an alternate supported dragging space
Is Draggable	Can child object be dragged from this container
Clone Dragged Object	If true, a copy is made of the original content when dragging, else it moves the original child content item
Is Dropable	Can objects be dropped in to this container
On Element Dropped (event)	The Event fired when a child item is released by a user
On Element Grabbed (event)	The Event fired when a child item is being held by the user
On Element Removed (event)	The Event fired when a child item is removed from a container
On Element Added (event)	The Event fired when a child item is added from a container

The properties of the individual Re-orderable List Items are as follows:

Property	Description
Is Grabbable	Can the object be grabbed from a re-orderable list
Is Transferable	Can the object be transferred from one re-orderable list to the next
Is Droppable In Space	Can the item be dropped outside of a re-orderable list. *note, once dropped outside they cannot be picked up again.

Usage

Simply add the default Re-orderable List control to the scene using one of the pre-built options in the Editor "GameObject" menu:

"UI / Extensions / Re-orderable Lists / Re-orderableList Vertical List"
"UI / Extensions / Re-orderable Lists / Re-orderableList Horizontal List"
"UI / Extensions / Re-orderable Lists / Re-orderableList Grid"
"UI / Extensions / Re-orderable Lists / Re-orderableList Vertical ScrollRect"
"UI / Extensions / Re-orderable Lists / Re-orderableList Horizontal ScrollRect"
"UI / Extensions / Re-orderable Lists / Re-orderableList Grid ScrollRect"

The base control is also available as a Game Component menu in "UI / Extensions / Re-orderable List". However, you will need to manually set up the control.
