Format the survey (package) intro text

Castor EDC allows you to format the text of some fields and survey intro and outro texts.

To edit the survey intro formatting, go to the 'Structure' tab and navigate to the 'Surveys' sub-tab:

Editing a survey package works in much the same way. To add formatting to the intro and outro texts, use the following markdown that applies to both survey and survey packages.

Keep in mind that you can always access this Markdown tutorial by clicking on 'help' text when editing a survey:

Text styling

Text is styled by using * and _ as shown:

_text_ or *text* is text

__text__ or **text** is text

Text size

Headers are styled by prepending #'s (one or more, depending on the size you prefer):

# Heading One
## Heading Two
### Heading Three
#### Heading Four
##### Heading Five
###### Heading Six

Will generate this output:

Heading One (H1)

Heading Two (H2)

Heading Three (H3)

Heading Four (H4)

Heading Five (H5)

Heading Six (H6)

For survey questions themselves, in certain circumstances (e.g. if you are using only specific field types in your surveys) we might be able to increase the size of the text. Contact us for further information.


Unordered (bulleted) lists use asterisks, pluses, and hyphens (*, +, and -) as list markers. It is necessary to use a space after each of the marker. These three markers are interchangable; this:

*   Candy.
*   Gum.
*   Booze.


+   Candy.
+   Gum.
+   Booze.

and this:

-   Candy.
-   Gum.
-   Booze.

all produce the same output:

· Candy.

· Gum.

·  Booze.

Ordered (numbered) lists use regular numbers, followed by periods, as list markers:

1.  Red
2.  Green
3.  Blue


1.  Red
2.  Green
3.  Blue

If you put blank lines between items, you’ll get tags for the list item text. You can create multi-paragraph list items by indenting the paragraphs by 4 spaces or 1 tab:

*   A list item.
    With multiple paragraphs.
*   Another item in the list.


·      A list item.

       With multiple paragraphs.

·       Another item in the list.

In order to create a hyperlink, use this format:

This is an [example link](

The output is:

This is an example link.

Image syntax is very much like the link syntax.

![alt text](/path/to/img.jpg 'Title')

The output is:

<img src='/path/to/img.jpg' alt='alt text' title='Title' />

Markdown supports two styles of headers, Setext and atx.

Setext-style headers are “underlined” using equal signs (for first-level headers) and dashes (for second-level headers). For example:

This is an H1

This is an H2

Any number of underlining =’s or -’s will work.

Atx-style headers use 1-6 hash characters at the start of the line, corresponding to header levels 1-6. For example:

# This is an H1

## This is an H2

###### This is an H6

Insert a new line or a empty line

A new line can be added with: 




First line
Second line

An empty line in between two lines can be added with an extra line break: 




First line

Second line
