To use it, CodeMirror must be disabled in the preferences, in the \emph{Authoring Space Configuration} section.

CKEditor is just an HTML editor, and it does not support LON-CAPA elements well, with the exception of \texttt{<m>} and \texttt{<chem>}, for which plugins have been added.
 \item The \emph{colorful editor} is LON-CAPA's default editor, launched when you click on the ``Edit'' button for a \texttt{.problem} file. It hides the source code and displays the document with colored boxes representing the elements. It provides a list of elements that can be inserted at a particular place in the document, helps to choose correct values when several values are possible for an attribute, and generally makes sure the syntax is correct.
 \item \emph{Daxe} is a new editor, meant to replace the colorful editor in the future. It is started with the ``Daxe'' button. Like the colorful editor, it hides the source code and provides a graphical interface which makes it easier to create documents without knowing the language. It displays elements in a better way, and makes it easier to edit documents with cut/copy/paste and drag \& drop features. HTML elements are often displayed exactly the way they look like in the end. Many response elements have both a ``simple'' and an ``advanced'' view, making it easy to create simple problems. A preview is available to the right, making it easy to see what the entire document will look like.

It is also possible to query for matches with optionresponse,
but optionresponse only accepts simple text for the matches.

such as equations, images, plots, or long styled texts.

The \texttt{foilgroup} must contain an \texttt{itemgroup} with \texttt{item} elements.

Possible attributes are:
\begin{itemize}
  \item \textbf{max}: the maximum number of foils displayed at once
  \item \textbf{randomize}: set to \texttt{yes} to randomize the order of foils when displayed
\end{itemize}
