ruby-on-rails – Rails ActiveAdmin,表单页面上的两列(不是侧边

如何在页面右侧添加“列”(不是侧栏),这样我最终会在左侧的表格中放置50％宽度的部分,在右侧放置50％宽度的部分？

我需要这个,因为我有很多领域.

这就是我的表格现在部分看起来像…

form do |f|
  f.inputs "Shipment Details" do
    f.input :file_number
    f.input :customer,:label_method => :company_name
    f.input :shipper,:label_method => :company_name
    f.input :broker,:label_method => :company_name
  end
    f.inputs "Places" do
    f.input :place_of_origin,:as => :select,:collection => Place.find(:all,:order => "city",:select => "city").map(&:city)
    f.input :place_of_loading,:select => "city").map(&:city)
    f.input :place_of_delivery,:select => "city").map(&:city)
    f.input :via,:select => "city").map(&:city)
  end
  f.inputs "Carrier" do
    f.input :carrier,:label_method => :company_name
    f.input :mode,:collection => ["Air","Air Collect","Air Prepaid","FCL","FTL","LCL","LTL","TBA"]
    f.input :mbl,:label => "MBL"
    f.input :hbl,:label => "HQL"
    f.input :vessel
    f.input :container
  end
  f.buttons
end
