All About Task Bundle and Nested Concept in Quire

Last updated: May 29, 2026

TL;DR: Quire's Nested Concept preserves parent-child task hierarchy across Tree view, Timeline view, and Board view (with Task Bundle). When you sort or group the list, subtasks stay attached to their parents instead of scattering. Most PM tools flatten hierarchy when you change views; Quire keeps it. Available on Professional and higher plans.

Talking about Quire means talking about the concept of hierarchical views. The nested task list might be the beginning of everything for Quire, however, we're now expanding the "nested concept" to many other views in Quire.

The case for hierarchical organization isn't new. According to Herbert Simon's 1962 paper The Architecture of Complexity, nearly all complex systems people understand at scale (biological organisms, organizations, software architectures, encyclopedias) are organized hierarchically, because hierarchy is what makes complexity navigable. Flat lists fail at scale not because lists are bad, but because human attention isn't built for hundreds of peer items at once. Quire's nested structure applies that finding to project task lists.

In case you don't know, Quire supports nested Kanban Board. You can learn more in this blog post.

What is Task Bundle in Nested List and Timeline views?

You might wonder here: what does it mean? Isn’t the nested concept already included in the List and Timeline views?

Well, it’s true if you’re having a “flat” list with no grouping or sorting option. The parent tasks and subtasks were separated when you grouped or sorted them by different criteria. However, in the latest update, the subtasks can remain with their parent tasks regardless of the sorting or grouping.

All you have to do is to enable the Task Bundle option after grouping or sorting your list. Now you don’t have to go look for your subtasks anymore, how great is that?

Task Bundle for Nested List and Timeline View is exclusively made for Professional and higher subscription plans. More information can be found on our Pricing page.

How does Quire's nested task support compare to other PM tools?

Most PM tools support subtasks. Where they diverge is whether the hierarchy survives sorting, grouping, and changing views.

The pattern: subtasks are common; preserving the hierarchy across views is rare. Quire's Task Bundle is the unusual part of this row, especially on Board view, where most tools just hide subtasks rather than show them attached.

How do Sections and Task Hierarchy interact in the Sorted view?

Just last month when Quire released Section and received a lot of positive feedback from our Quireans. You might notice the sections were detached from their tasks if you choose to sort your task list.

With the latest updates in Quire, your task list's hierarchy will remain within sections if grouped or sorted. Now you can continue your work and see everything in perspective.

In Timeline view, the sections also remain attached to the tasks when sorted or grouped.

Why is the Nested Concept important in Quire?

You might ask, why did we go the extra mile just to enhance a simple concept? From the beginning, we’re persuaded and put our trust in the nested concept. We don’t believe in a flat laundry list. Quire is built around the idea of every task in your list should be related and you’ll get a better big picture of your goal if your tasks are logically linked.

Preserving the task hierarchy under any circumstances is important since the original hierarchy of your task list has a meaning and should be retained at any time. Instead of taking the subtasks away from their precedents, we try to keep you the original hierarchy so you always know the relationships among all the tasks.

The best thing about Task Bundle and Nested Concept in Quire, you may ask, is the flexibility. Of course, if you believe in task hierarchy like us, you can toggle on the task bundle option. However, if you think of each task as an independent property, just toggle off and continue the flat layout of your projects. Whatever works better for you, you’re always in control of your task list.

When does the Nested Concept get in the way?

Three patterns where nesting hurts more than it helps.

• Your work is genuinely flat. A daily checklist of independent reminders ("call dentist," "buy groceries," "submit timesheet") doesn't have parent-child relationships. Forcing hierarchy on it creates fake structure. Use a flat list and let the tool be light.
• Your team disagrees about which tasks are subtasks of which parents. If two people would model the same project with different hierarchies, the structure isn't natural yet. Spend ten minutes agreeing on the shape before nesting anything, or your nested list will become a source of arguments.
• You're using nesting as a substitute for tags. A task like "marketing landing page" doesn't need to be a subtask of "Marketing." It needs a tag. Nesting is for parent-child work relationships, not for category membership.

If your project has real parent-child work decomposition, Quire's Nested Concept will keep that structure visible across every view you switch to.

Ready to keep your hierarchy intact across every view?

If you've been losing your nested structure when you switch from List to Board or Timeline, toggle on Task Bundle on a real project and see what changes. Most teams notice the difference within the first five minutes of working in the new view.

Task Bundle for Nested List and Timeline is on Professional and higher Quire plans. The pricing page covers the tier details.
