Height Select Box

/ Published in: Rails

Put the height_options method into a helper file, and use it as the select collection for select or collection_select.

It allows heights between 4 feet and 7 feet. To change these limits, change 48 and 84 to some other numbers.

Copy this code and paste it in your HTML

def height_options
    heights = Hash.new
 
    for n in 48..84
      feet = (n/12).floor
      inches = n % 12
      heights[n] = "#{feet}'#{inches}''"
    end
 
    return heights.to_a.sort.map { |h| h.reverse }
end
