Example

options = [‘Male’, ‘Female’] o.select(:name => ‘sex’) { o.options(options, selected = 1) }

options = { ‘Male’ => ‘m’, ‘Female’ => ‘f’ } o.select(:name => ‘sex’) { o.options(options, selected = 1) }

def options(opts, selected = nil)
	if opts.is_a?(Array)
		selected = selected.to_i
		opts.each_with_index do |label, value|
			if value == selected
				self << %|<option value="#{value}" selected="1">#{label}</option>|
			else
				self << %|<option value="#{value}">#{label}</option>|
			end
		end
	else
		opts.each do |label, value|
			if value == selected
				self << %|<option value="#{value}" selected="1">#{label}</option>|
			else
				self << %|<option value="#{value}">#{label}</option>|
			end
