A table containing data used by the type parameter of the message box. The table keys are the values that can be passed to the type parameter, and the table values are tables containing the class and the image used by that type.
default
The type to use if no value was passed to the type parameter, or if an invalid value was specified.
showInvalidTypeError
Whether to show an error if the value passed to the type parameter was invalid.
allowBlankParams
Usually blank values are stripped from parameters passed to the module. However, whitespace is preserved for the parameters included in the allowBlankParams table.
allowSmall
Whether a small version of the message box can be produced with |small=1.
smallParam
A custom value for the |small= parameter. For example, if set to <syntaxhighlight inline="1" id="" class="" style="" lang="lua">"left"</syntaxhighlight> you can produce a small message box using |small=left.

The class to use for small message boxes.
substCheck
Whether to perform a subst check or not.
