module Playbook

    # Renders a pb form with ::Playbook::Forms::Builder, that can render
    # Playbook kits in the most railsie way.

    #
    #   pb_form_with model: @user do |f|
    #     f.text_field :name

    #
    #   pb_form_with model: @user, validate: true do |f|
    #     f.text_field :name, required: true
    #   end

    # @param validate [Boolean] whether validation should be triggered or not
    # @see [#form_with] for other options
