# Mark Tasks Without Resource Allocation

> Identify unassigned tasks at a glance in Nextedy GANTT by enabling visual indicators that highlight work items missing a resource allocation.

export const LastReviewed = ({date}) => {
  if (!date) return null;
  const formatted = new Date(`${date}T00:00:00Z`).toLocaleDateString("en-US", {
    year: "numeric",
    month: "long",
    day: "numeric",
    timeZone: "UTC"
  });
  return <p className="mt-10 text-sm text-gray-400 dark:text-zinc-500 not-prose">
      Last reviewed on {formatted}
    </p>;
};

## How No-Allocation Marking Works

When a task has no assignee, the Gantt chart applies two visual indicators:

1. **Red task bar background** -- the task bar in the Gantt chart receives a red highlight, making it immediately distinguishable from assigned tasks
2. **Grey resource view cell** -- in the resource view, cells for unallocated tasks display with a grey background instead of the usual green or red allocation markers

These indicators help project managers quickly spot work items that need assignment during planning sessions.

| Task State                | Task Bar                      | Resource View Cell |
| ------------------------- | ----------------------------- | ------------------ |
| Assigned, within capacity | Standard color                | Green marker       |
| Assigned, overallocated   | Standard color                | Red marker         |
| No assignee (active)      | Red highlight                 | Grey cell          |
| No assignee, status Done  | Standard color (no highlight) | No indicator       |

<Note title="Done Tasks Are Excluded">
  Tasks with a **Done** status are exempt from the no-allocation marking even if they have no resource assignment. This prevents completed items from cluttering the view with false warnings.
</Note>

<Steps>
  <Step title="Enable the Resource View">
    To see both the task bar and resource view indicators, enable the resource view in your Gantt widget parameters:

    1. Open the Gantt widget parameters
    2. Set **Show Resource View** to `Yes`
    3. Configure the **Resource Field** (defaults to `assignee`)
  </Step>

  <Step title="Enable the Show Unassigned Row">
    To see unallocated tasks grouped in the resource view:

    1. In the widget parameters, set **Show Unassigned** to `Yes`
    2. This adds a dedicated row in the resource view for all work items that have no value in the resource field

    <Tip title="Combine with Resource Hiding">
      If you use the [Hide Inactive Resources](/gantt/guides/resources/resource-hiding) feature, the Unassigned row remains visible as long as there are unassigned tasks, making it easy to spot items needing attention.
    </Tip>
  </Step>

  <Step title="Review Unallocated Tasks">
    With the configuration in place:

    1. Open the Gantt chart and look for task bars highlighted in red -- these are tasks without an assignee
    2. Check the resource view for grey cells indicating unallocated time periods
    3. Open any highlighted task in the lightbox to assign a resource

    <Warning title="Filtered Items and Resource Calculations">
      Work items that are filtered from the task list but not hidden may still contribute to resource view markers. If you see unexpected grey cells, check your active filters to ensure items are not being filtered out of the task view while remaining in resource calculations.
    </Warning>

    <Warning title="Orphaned Team Assignments">
      If you use team assignments, ensure all team assignment work items are properly linked to their parent team. Unlinked team assignments can cause grey capacity indicators that appear similar to the no-allocation markers but indicate a configuration issue rather than a missing assignee.
    </Warning>
  </Step>
</Steps>

## Verification

You should now see:

* Task bars with no assignee highlighted in red in the Gantt chart
* Grey cells in the resource view for unallocated time periods
* Completed (Done) tasks displaying normally without the red highlight, even if they have no assignee
