With this API, Simple Form will be possible to add custom components.
Methods defined in a component will be exposed to be used in the
wrapper as Simple::Components
Examples
# The application needs to tell where the components will be.
Dir[Rails.root.join('lib/components/**/*.rb')].each { |f| require f }
# Create a custom component in the path specified above.
# lib/components/input_group_component.rb
module InpoutGroupComponent
def preprend
...
end
def append
...
end
end
SimpleForm.setup do |config|
# Create a wrapper using the custom component.
config.wrappers :input_group, tag: :div, error_class: :error do |b|
b.use :label
b.optional :prepend
b.use :input
b.use :append
end
end
# Using the custom component in the form.
<%= simple_form_for @blog, wrapper: input_group do |f| %>
<%= f.input :title, prepend: true %>
<% end %>
