Add a new select_prompt method

[jwoertink]

If you're using select_tag and rending all your options, there's no easy way to currently set your prompt. It would be neat to have a select_prompt method so we don't just bloat the current options_for_select with options.

select(op.opts) do
  select_prompt("Select your option")
  options_for_select(op.opts, my_options)
end

My thought is this method would only generate:

<option value="">Select your option</option>

If your prompt option is first, then it will display that, unless you have a selected option. The selected option would get set from your options_for_select, and then it would default to that.

Another way could be to pass in the attribute so you could not render the field if there's a value, but then you'd never be able to "unselect" your value....

select_prompt(op.opts, "Select your option")

Thank you for creating this! I think both options should be available. The one that removes the option if a value was selected is nice when select a blank value is invalid, so it should only show “Select your option” for brand new records.

ah! Yeah, I guess that's true too. You might not want someone to select a blank value if the record already exists. Good thinking!

This would be nice. I frequently use multiple options_for_selects.

This took me some time to figure out initially because I was expecting a prompt argument or something similar. It might not hurt to mention this way in the docs for when there are more complex requirements.

options_for_select @save_user.manager_id, [{"", ""}]
options_for_select @save_user.manager_id, @manager_options
