In Rails, we use collection_select helper to display values from a particular model using a drop down but it is generally tied to a particular model, i.e. if we look at the generated html then we see something like
select name="customer[customer_search]" id="customer_customer_search"
What if we want something like:
select name="customer_search" id="customer_search"
Then we can simply use select_tag helper and get the values from our model like this
customers = Customer.find(:all, :order => 'first_name').map{|x| [x.full_name] + [x.id]}
select_tag(:customer_search, options_for_select(customers))
If we don’t want to display the values from model and would like to feed in something simple and manually, then
customers = [['text_to_display1', 'value1'], ['text_to_display2', 'value2']]
select_tag(:customer_search, options_for_select(customers))
If text_to_display and its value both are same then we can use something as simple as:
customers = ['wee', 'asdf']
select_tag(:customer_search, options_for_select(customers))
