.SH DESCRIPTION
.IX Header "DESCRIPTION"
Causes a single submitted value to be changed to a list containing 1 item.
.PP
Solves an uncommon problem with a
Repeatable block with
increment_field_names
disabled, when manually increasing the
repeat count after the form was
submitted with only a single value for each of the Repeatable's fields.
.PP
If these circumstances, when rendered, every repeated field would have the
initially-submitted value as its default.
.PP
Using this filter, and setting
render_processed_value to \f(CW\*(C`true\*(C'\fR will
ensure that only the first repetition of each field will have the submitted
value as its default; all subsequent repetitions will have no default value.
