How to make Twitter bootstrap tooltips have multiple lines?

I am currently using the below function to create text that will be displayed using bootstrap's tooltip plugin. How come multiline tooltips only works with

<br>
and not
\n
? I prefer that there is not any html in my links' title attributes.

What works

def tooltip(object)
tooltip = ""
object.each do |user|
tooltip += "#{user.identifier}" + "<br>"
end
return tooltip
end


What I want

def tooltip(object)
tooltip = ""
object.each do |user|
tooltip += "#{user.identifier}" + "\n"
end
return tooltip
end

Answer

You can use white-space:pre-wrap on the tooltip. This will make the tooltip respect new lines. Lines will still wrap if they are longer than the default max-width of the container.

.tooltip-inner {
    white-space:pre-wrap;
}

If you want to prevent text from wrapping, do the following instead.

.tooltip-inner {
    white-space:pre;
    max-width:none;
}

Neither of these will work with a \n in the html, they must actually be actual newlines. Alternatively, you can use encoded newlines &#013;, but that's probably even less desirable than using <br>'s.
