SYNOPSIS

13           element:
14             - type: Repeatable
15               increment_field_names: 0
16               elements:
17                 - name: foo
18                   render_processed_value: 1
19                   filter:
20                     - ForceListValue
21

DESCRIPTION

23       Causes a single submitted value to be changed to a list containing 1
24       item.
25
26       Solves an uncommon problem with a Repeatable block with
27       increment_field_names disabled, when manually increasing the repeat
28       count after the form was submitted with only a single value for each of
29       the Repeatable's fields.
30
31       If these circumstances, when rendered, every repeated field would have
32       the initially-submitted value as its default.
33
34       Using this filter, and setting render_processed_value to "true" will
35       ensure that only the first repetition of each field will have the
36       submitted value as its default; all subsequent repetitions will have no
37       default value.
