How to collapse mind map branches

Fold a branch with the chevron

Canvasola puts a chevron on a node so you can fold what sits below it. Clicking that chevron folds everything under the node into a single label, so a branch with thirty leaves becomes one line on screen. The structure is not deleted, it is hidden, and clicking the chevron again brings the whole branch back exactly as it was.

Collapsing is the fastest way to make a finished map readable. A map with two hundred open nodes is a working document, while a map with twenty visible branches is a slide. The same content supports both; only what is open changes.

Each node keeps its own expanded state, so a folded branch stays folded while you move around the map, switch tabs and come back. That is what makes collapsing usable as a working habit rather than a one-time cleanup: you fold the branch you are not working on, and it stays folded.

• The chevron on a node folds everything underneath it
• Click the chevron again to unfold, with nothing lost
• Every node remembers whether it is open or folded
• Folding changes what is on screen, not what is in the map

Collapse everything under one node

Sometimes the problem is not a single branch but an entire region. Collapsing a node near the top folds that whole region in one action, and it is the quickest route from a sprawling map to a reviewable one when you are about to present it or hand it to someone else.

Fold at the level where the meaning changes. If your map has a Research branch with a dozen children, and each of those has children of its own, folding Research gives you one line in the outline, and the reader can ask to open it. Folding each grandchild instead leaves a page of half-lines.

Collapsing is reversible and cheap, so it is safe to experiment. If you folded too much, click the chevron again. If you folded too little, collapse the parent instead. If a region keeps needing to be folded and reopened, the branching rules guide has a better answer than more folding.

• Collapsing one level up turns a region into a single line
• Fold at the level where the meaning changes for your reader
• Unfolding restores the exact subtree you folded
• Collapsing is safe to experiment with, because nothing is deleted

Expand All and Collapse All

Expand All and Collapse All set the entire map in one move. They are the two commands you reach for when you have just finished a round of editing and want to see the whole structure, or when you want a clean overview to work from. Neither one destroys anything; they only change what is open.

Use Expand All as a review step. Opening everything is how you spot the branch that quietly grew to nine levels while you were not looking, and the label that turned into a sentence. Read the fully expanded map once, then fold it back down to the level you actually work at.

Use Collapse All as a reset. It leaves you with the root and its immediate children, which is the smallest useful view of a map and a good place to decide which branch to open next. If even the collapsed view is dense, the map may be too large for one layer, and splitting it into layers gives you a smaller map to fold.

• Expand All is a review tool, not a working state
• Collapse All leaves the root and its immediate children
• Both commands are reversible in a single click
• Collapse All, then open one branch, is a fast daily routine

Keep the shape of a folded map in mind

A folded map hides its structure, and that is the point, but it also removes your sense of where things are. The fix is to keep the parent label informative. After collapsing a branch, glance at the parent: if it says only "Research", you have lost the fact that it held four different threads.

Two habits keep that memory alive. First, make sure the parent label stands on its own, because a folded branch is read as one line in the outline. Second, put a short summary of what was inside in the parent's note, so opening the note still tells you what the branch covered.

A third habit is to collapse in a consistent order. If you always fold from the bottom upward, you build a spatial memory that survives the collapse. Folding at random produces a map where you cannot tell whether missing content is off screen or folded away. The shortcut list also includes F, which fits the content to the view.

• A folded branch is read as one line, so the label must stand alone
• Keep a short summary of the branch in the parent's note
• Fold in the same order every time so the map keeps a mental shape
• Say what you just folded, it takes two seconds

Use the minimap to stay oriented

Press M and a small overview of the whole map appears in the corner. It shows the entire tree, including the parts that are folded and the parts that are off screen, and clicking a point in it jumps the camera there. It is the cheapest answer to the question a big map always raises: where am I, and what is left?

The minimap earns its place right after a collapse, because folding changes the size of the map and the camera can end up pointing at empty space. Clicking the minimap pulls the view back to the shape of the whole thing in one gesture, which is faster than re-finding the map by eye.

Because the minimap shows the real shape of the map, it also tells you when the map has grown lopsided. A tree twice as wide on the right as on the left usually means one branch has become a dumping ground. Seeing that in the overview is a prompt to rebalance and fold that branch away properly.

• M toggles the minimap in the corner
• Click the minimap to jump the camera to any part of the map
• The minimap shows folded and off-screen branches too
• A lopsided overview usually means one branch is overloaded

Collapse before you present

Presentation mode opens on the root label and then shows one slide for each first-level branch, showing its immediate children. If the branches are still expanded, each slide carries far more than it needs to, and the extra lines compete with the branch label you actually want read.

So fold before you present, not during. Decide which level each first-level branch should show, collapse anything deeper, and check that a slide reads as a headline plus a short list. Press P to enter presentation mode, Space or ArrowRight to advance, ArrowLeft to go back and Esc to exit.

A folded map also presents faster, because there are fewer visible nodes to lay out. If the presentation feels busy, the fix is usually three more chevron clicks rather than a different deck. The presenting a mind map guide covers the walkthrough in full.

• Collapse so each slide shows a label and a short list
• P starts presentation mode and Esc leaves it
• ArrowRight or Space advances, ArrowLeft goes back
• Fold the branches you are not presenting

A checklist you can reuse

• The branch you are not working on is folded with its chevron
• Every node still shows its own expanded state after a reload
• Expand All was used once as a review, then the map was folded back down
• Each folded parent label still makes sense on its own
• A summary of each folded region is stored in the parent's note
• The minimap is on with M whenever the map is large
• Branches were collapsed to the right depth before presentation mode started

Common mistakes to avoid

• Collapsing instead of restructuring. If you are constantly folding and reopening the same region, the branch is in the wrong place. Move it under a better parent instead of hiding it.
• Parent labels that mean nothing alone. A folded branch is read as a single line, so a parent called "Stuff" tells the reader nothing once the children are hidden. Name it for what it holds.
• Leaving the map fully expanded. A map with every node open is a working document, not something you can review or present. Fold it back to the level you read at.
• Losing the overview while zoomed in. Working deep in a map without the minimap is how you end up unsure where you are. Keep M available and click the overview to pull the camera back.
• Folding during a presentation. Folding as you present means the audience watches the structure change. Collapse before you start, check each slide, then press P.

Frequently asked questions

Does collapsing a branch delete its content?

No. Collapsing hides the descendants on screen and keeps them in the map, and every node stores its own expanded state so it stays folded. Clicking the chevron again brings the whole subtree back exactly as it was before, with every child in place.

How do I see the whole map when most of it is folded?

Press M for the minimap. It draws the entire tree including folded and off-screen branches, and clicking a position in it jumps the camera there. Pressing F fits the content to the view for the same purpose, and both work while a map is active.

Can I collapse a branch and still search inside it?

Yes. Folding affects what is drawn, not what is stored. Ctrl/Cmd+F searches node labels and notes across the map, and a jump to a node inside a folded branch opens it, so you can see the result you searched for.
