REDCap External Module: Choice Columns

Luke Stevens, Murdoch Children's Research Institute https://www.mcri.edu.au

Summary

Tag radio or checkbox fields with the action tag @CHOICE-COLUMNS=? to specify the number of columns the choices will be displayed in.

Notes:

The tag is ignored for fields other than radio and checkbox.
The tag is ignored for radio and checkbox fields that are part of a matrix.
Enhanced radio buttons and checkboxes are supported.
Specify an integer in the range 1-99 for the number of columns. Any other value will cause the tag to be ignored and the field display default behaviour.
Piping into the action tag is supported, but only on page load. It is not dynamic within a page (i.e. is similar to other tags like @HIDECHOICE and @IF).

Horizontal: Choices will be displayed in columns with choices listed across then down.
Vertical: Choices will be displayed in columns with choices listed down then across.

Note: down then across filling for fields with vertical alignment means that the specified column count may not be fully filled.

Left: Recommended. Choices occupy the full width of the form container, with the field label above.
Right: Choices occupy space to the right of the field label. Usually unsuitable with higher column counts.

The module is designed to support re-rendering following language changes, including between left-to-right and right-to-left languages.
