3. Build the outline

Goal: build a real course structure and prove every way of rearranging it holds.

Prerequisite: flow 1 done. Work in the Course Content section of the workspace.

This is the densest surface in the product and the one most likely to hide a bug. Take it slowly.

The two modes

The toggle on the right of the Course Content header switches between Edit and Reorder. It is not cosmetic — each mode exposes a different set of row actions, and an action missing from one mode is not a bug.

	Edit	Reorder
Rename a title inline	yes	no
Drag handle	no	yes
Move up / Move down	no	yes
Move to module	no	yes (activities only)
Add new item / Add content	yes	no
Duplicate / Remove	yes	no

Adding content

Three entry points, and they do different things:

Control	Where	Adds to
Add Module (folder+ icon)	Course Content header	course root
Add Content (file+ icon)	Course Content header	course root
Add new item	a module’s own row, Edit mode	inside that module

The Add Content dialog is a quantity picker, not a single-item picker. Seven types — Lesson, Quiz, Survey, Assignment, Forum, Meeting, External Course — each with a stepper. The count is typeable and goes up to 99 per type, and one submit can mix types.

Steps

1. From the empty state, click Add Module. Rename it.
2. Add a second module.
3. On module 1, use Add new item and add 3 Lessons in one go — set the Lesson stepper to 3 and click Add.
4. On module 2, add 1 Quiz and 1 Survey in the same submit.
5. From the header, click Add Content and add 1 Lesson — it lands at the course root, not inside a module.
6. Add a module inside module 1 (modules can nest).

What to check

• Three lessons arrive as three separate rows, not one.
• Mixed submit creates both the quiz and the survey.
• Header Add Content lands at root; module Add new item lands inside the module.
• Every new row gets a default title and the activity count in Course at a glance keeps up.

Edit mode

Renaming

Click the title once to arm it, click again to focus it, type, then press Tab or click away. The blur is what saves — typing alone does not.

Row actions

Row	Actions
Module	Add new item, Remove
Activity	Add content (opens that activity’s editor), Duplicate, Remove

Remove always asks for confirmation. Duplicate copies the row in place.

On narrow screens the individual buttons collapse into a single ⋯ menu with the same actions — worth one pass at phone width.

Expanding and collapsing

The folder icon in the header toggles Expand all / Collapse all. Individual modules toggle by clicking the module header, or with Enter / Space when it has focus.

Steps

1. Rename a module and a lesson. Reload and confirm both stuck.
2. Duplicate a lesson. Rename the copy and confirm the original did not change.
3. Remove a lesson, confirm the dialog appears, accept.
4. Remove a module that still has activities inside it.
5. Collapse all, expand all, then toggle one module on its own.

What to check

• Renaming survives a reload.
• The duplicate is independent of the original.
• Removing a module takes its children with it, and the counts update.
• Cancelling the confirmation removes nothing.

Reorder mode

Switch the toggle to Reorder. The row actions change and a drag handle appears on the left of each row.

Three ways to move an item

1. Drag and drop — grab the handle and drop the row where you want it, including into or out of a module.
2. Move up / Move down — the arrow buttons on the row. This is the keyboard-reachable path: Tab to the arrow, press Enter. Test this one; it is the path that gets skipped.
3. Move to module — activities only. Opens a dialog.

Module rows only get the arrows — no Move to module, since a module has nowhere else to go.

The Move to module dialog

• A position toggle: Beginning of module or End of module (defaults to End).
• The list of target modules. The item’s current parent and the item itself are excluded — so a lesson already in module 1 will not offer module 1.
• A Root entry, shown only when the item currently sits inside a module — that is how you pull something back out to the top level.
• Move stays disabled until a target is picked.

Nesting rules

Nesting is capped at 4 levels, and modules may contain modules. An invalid drop is rejected with a named error, and each message is a distinct case worth reproducing:

Message	What you did
Cannot move a lesson into one of its sub-lessons	dropped a parent into its own child
Cannot move a lesson to a location containing its sub-lessons	dropped onto its own subtree
Cannot move this lesson here - it would exceed the maximum nesting level	went past level 4
Cannot move this module here - it would cause some lessons to exceed the maximum nesting level	moved a module whose children would go past level 4

Steps

1. Drag a lesson from module 1 to module 2.
2. Drag it back using only Move up / Move down.
3. On a lesson inside a module, use Move to module → Beginning of module and confirm it lands first, not last.
4. Use Move to module → Root on a nested lesson.
5. Nest modules until you hit level 4, then try to go one deeper.
6. Try to drag a module into one of its own children.
7. Switch back to Edit and reload the page.

What to check

• The order after a reload matches the order you left, for all three move methods.
• Beginning of module really puts the item first.
• The current module is absent from the dialog list; Root appears only for a nested item.
• Invalid moves show the message above and change nothing — no half-move.
• Arrow buttons are reachable and operable by keyboard alone.

Caution

A move that appears to work but reverts on reload is the highest-value bug on this page. Always reload after reordering.

Batch mode

The Batch button next to the mode toggle turns on multi-select. The bar then shows N selected plus Select all, Deselect all, Delete selected and a button to leave batch mode.

Selecting a module selects every descendant with it — that is deliberate, not a bug. Dragging is disabled while batch mode is on.

Steps

1. Turn on Batch. Select a single lesson, then a module.
2. Confirm the module’s children were selected too and the count reflects it.
3. Deselect all, then Select all.
4. Select two lessons and Delete selected.
5. Leave batch mode and try to drag — then switch to Reorder and try again.

What to check

• The count matches what is actually highlighted.
• Deleting removes exactly the selection, nothing adjacent.
• The mode toggle and row actions are hidden while batch mode is on.
• Dragging does nothing in batch mode, and works again once it is off.

Where it usually breaks

• Reordering, then leaving the page before the save lands.
• Drag into a nested module landing at the wrong depth.
• Move to module offering the module the item is already in.
• Batch delete taking a neighbouring item along with the selection.
• The activity count in Course at a glance drifting out of sync after removals.
• Two tabs open on the same course — the second overwrites the first.
