Expand
An expand is a section that starts closed. Readers see only its title, with an arrow, and click it to open the rest. It keeps a long page short: the detail is there for the few who need it, and everyone else reads straight past. Frequently asked questions, long logs, reference tables and “how this works underneath” all fit well.
Insert it
Type this | To get |
|---|---|
/expand | An expand |
/collapse | An expand |
/details | An expand |
Type the command at the start of an empty line and press Enter. Type the title in the box at the top, press Enter to move into the body, and write what it holds. Or choose + on the toolbar, then Expand. If you select text first and use the + menu, the selected text goes inside the expand.
Kinds of expand, and when to use each
Each example below is closed, as readers see it. Click a title to open it.
Questions and answers
A list of questions, each opening to its answer. A reader scans the questions and opens only the one they came for.
The detail behind a summary
The import finished with one warning: three pictures were too large and were skipped.
Say the result in the text, and put the evidence in an expand: the full log, a long table, the raw figures behind a chart. An expand can hold anything a page can: lists, tables, code, pictures, even panels.
An expand inside an expand
Detail inside detail, such as a troubleshooting section with one expand for each problem. One level inside another is plenty: any deeper, and readers lose track of what they have opened.
Open while you edit, closed for readers. An expand is always open in the editor, so you can see and change what is in it, and always starts closed when the page is read. A reader opening one opens it only for themselves.
Changing and removing an expand
While you edit, click the title to change it. Click inside the expand and a small bar appears above it with Remove expand, which takes the expand away and keeps everything that was in it, as ordinary content.
Good practice
Say what is inside. Full import log (5 lines) lets a reader decide without opening it; Details does not.
Always give it a title. One without a title reads “Click to expand”, which tells nobody anything.
Do not hide what everyone needs. Steps everyone must follow and warnings belong in plain sight.
Put the key words in the title. The browser’s own Find (Ctrl+F) does not look inside a closed expand.

Panels make something stand out rather than hiding it.
Headings divide a page into sections that are always open.
Code block is the best way to show a log inside an expand.
