Starting with version 8.0.0, OpenProject features a quasi-WYSIWYG editor, powered by CKSource CKEditor5. The underlying format is GitHub-flavored CommonMark (GFM). All previous textile-based content will be migrated when upgrading to OpenProject 8.0.

Basic formatting

The CKEditor5 build in OpenProject supports basic text styles, such as bold and italic formatting, headings, inline code and quotes as well as inline image handling. Pasting content such as images or rich text is also supported, while unsupported styling will be stripped by the editor.


Create hyperlinks by pressing the toolbar (optionally with some selected text), or by pressing CTRL+k to open a popup to enter the link href.

Widgets and Newlines

CKEditor usese widgets to display block elements such as images, tables, and other elements that are not inline. You can select most widgets by pressing on it - The only exception to that is the table widget, it has a little select knob at the top left to select the entire table.

When you have a widget selected, you can remove or cut it. You can create a newline below it by selecting the widget and pressing ENTER, or a newline above it by pressing SHIFT+enter. This is especially needed when the widget is the first or last element on the page to insert a line below or above it.

Code Blocks

As CKEditor5 currently does not provide support for code blocks, OpenProject can display, but not edit code blocks within the CKEditor instance. A code block can be edited through a modal window within a CodeMirror editor instance. This has the advantage of providing syntax highlighting and code sensing (for supported languages).


The GFM extension of the CommonMark specs adds a definition for table syntax which the CKEditor build of OpenProject supports. This definition requires all tables to have a heading row. For tables created with CKEditor without heading rows, a HTML table is output instead. This matches the behavior of, e.g., GitHub.


CKEditor5 allows certain CommonMark-like autoformatting keyboard strokes:

  • Create bold or italic styles by typing **will become bold**, _will become italic_,
  • Create heading of different indentation with #, ##, ###, …
  • Create a bulleted list by starting the line with * or - and a space
  • Create a numbered list by starting the line with 1. or 1) and a space

Inline (Balloon) editor

In some resources such as work packages, the editor is shown using an inline / balloon style toolbar. To enable the toolbar, either select text in the editor, or double click on an empty area in the editor pane.

Image handling

In supported resources of OpenProject where attachments are allowed, you can add images to the page by either

  • using the toolbar button,
  • pasting an image from your clipboard,
  • or drag & drop an image onto the editor.

The attachment will be automatically uploaded and stored as an attachment.


OpenProject has supported macros on textile formatted pages and continues to do so with the WYSIWYG editor. Note that macros are not expanded while editing the page, instead a placeholder is shown.

Table of contents

Where applicable, the table of contents (TOC) macro will output a listing of all headings on the current page.

Work package button

Configure a button or link to target the work package creation screen in the current project. You can preselect a work package type that should be selected, making it easy to guide the users to the work package creation form.

Include wiki page

Include the content of a given wiki page in the current, or another visible project.ww

Embed work package table and Gantt chart

This is the most flexible macro that provides extensive functionality regarding the inclusion of dynamic work package tables with all the potential of the regular work package table.

By adding an embedded work package table through the toolbar, you can configure the table view (such as columns, grouping, filters, and further properties) in a popup window.

The rendered page will then fetch the work package table results dynamically, respecting the visibility for each user.

Use it to embed views in other pages, create reporting of multiple results, or to embed a Gantt chart view.

Links to OpenProject resources

As with the textile formatting syntax, you can link to other resources within OpenProject using the same shortcuts as before. Create links to a:

  • wiki page: [[Wiki page]]
  • wiki page in the Sandbox project: [[Sandbox:Wiki page]]
  • work package with ID12: #12
  • work package with ID 12 with subject and dates: ##12
  • work package with ID 12 with subject, assignee, description, and dates: ###12
  • version by ID or name: version#3, version:"Release 1.0.0"
  • project by ID/name: project#12 , project:"My project name"
  • attachment by filename:
  • user by id or login: user#4 , user:"johndoe"
  • a forum message by ID: message#1218
  • repository revision 43: r43
  • commit by hash: commit:f30e13e4
  • To a source file in the repository: source:"some/file"

Autocompletion for work packages and users

For work packages and users, typing # or @ will open an autocompleter for visible work packages and users, respectively.
