module Decidim
# This cell renders a collapsible list of elements. Each element from the
# `model` array will be rendered with the `:cell` cell.
#
# Available sizes:
# - `:small` => collapses after 3 elements.
# - `:default` => collapses after 7 elements. If not specified, this one is
# used.
#
# Example:
#
# cell(
# "decidim/collapsible_list",
# my_list,
# cell_name: "my/cell",
# cell_options: { my: :options },
# hidden_elements_count_i18n_key: "my.custom.key",
# size: :small
# )
