# Separate "being worked" from "ready to move on"

Two change requests sit in **In Review**: one is still being reviewed, the
other was reviewed yesterday and is waiting for whoever picks it up next. Same
state, different situation. Splitting the column shows the difference without
adding a state to your process.

## Before you start

A boolean field on the work item type. The demo process uses
`Custom.BoardColumnDone`. Adding a field is a process change, so it is an
administrator's act, done by hand ([Prerequisites](https://anykanban.com/docs/prerequisites/)) or by
executing the plan the organization settings page composes. **AnyKanban never
changes your process without that click.**

## Steps

1. Open the board and select **Settings**.
2. Open **Columns** in the left rail, under **Board**.
3. Pick the field under **Done-flag field**, above the strip of column tabs.
   The list
   offers the boolean fields you added to the type, meaning your custom ones.
   Native and hidden fields are never offered. Nothing is typed by hand, so
   the stored name is one the service itself reported, and a typo cannot
   strand the board. If the panel says the type has no boolean field yet, the
   field from *Before you start* has not been added.
4. A **Split into Doing / Done** checkbox now appears in every column's form.
   Select the column you want split in the strip, which on the demo's cross-project
   change request board is **In Review**, and tick it.
5. Select **Save**.

## What you should see

The column renders two labeled sub-lists, **Doing** and **Done**, and cards
are partitioned by the field's value: on the demo board "Unify customer
identifiers across policy and claims" sits under Doing and "Straight-through
payout below €500" under Done. Each side is its own drop target, and the column
as a whole stops being one: you always drop on one side or the other.

Dropping a card on **Done** writes `true` into the field; dropping it on
**Doing** writes `false`. The write rides in the same operation as the state
and rank changes the drop implies, so a card that moves into the column and
lands on Done is one write, not two.

## Notes

Moving a card out of a split column resets the flag to `false` in the same
write, so a card can never arrive elsewhere still marked done. Clearing the
done-flag field on save clears every split column with it. Because the flag is
a real field rather than a hidden board attribute, you can query and chart it,
which is the reason it is bound to a field you own.
