Tips on creating Twitter Bootstrap tooltips with multiple lines:

I have been using the function below to generate text for Bootstrap's tooltip plugin. Why is it that multiline tooltips only work with <br> and not \n? I would prefer to avoid having any HTML in my links' title attributes.

Current Solution

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

Desired Solution

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

Answer №1

To maintain new lines in a tooltip, you can apply white-space:pre-wrap. This CSS property will ensure that the tooltip respects line breaks. However, if a line is too long for the container's default max-width, it will still wrap.

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

For text that should not wrap at all, use the following CSS instead:

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

Keep in mind that neither method will work with a \n within the HTML - actual newlines are required. An alternative approach could be using encoded newlines like &#013;, although this may be less desirable than using <br>.

For utilizing the html feature, refer to this link: http://jsfiddle.net/UBr6c/

My <a href="#" title="This is a<br />test...<br />or not" class="my_tooltip">Trying out a Tooltip</a> example.

$('.my_tooltip').tooltip({html: true})

Answer №3

If you are utilizing the Twitter Bootstrap Tooltip on a non-link element, you have the option to indicate that you desire a multi-line tooltip directly in the HTML code without the use of Javascript by simply using the data parameter:

<span rel="tooltip" data-html="true" data-original-title="1<br />2<br />3">5</span>

This serves as an alternative version of costales' response. He deserves all the credit! :]

Answer №4

If you are working with Angular UI Bootstrap, you have the option to use tooltips with HTML syntax by simply using tooltip-html-unsafe

For example: upgrade to angular 1.2.10 and angular-ui-bootstrap 0.11: http://jsfiddle.net/aX2vR/1/

previous version: http://jsfiddle.net/8LMwz/1/

Answer №5

With the latest version of Angular UI Bootstrap (0.13.X), the deprecated tooltip-html-unsafe has been replaced with tooltip-html. To create a tooltip with HTML content, use $sce.trustAsHtml().

Check out the changes on GitHub

<a href="#" tooltip-html="htmlTooltip">Hover over me!</a>

$scope.htmlTooltip = $sce.trustAsHtml('I am now displayed in <b>bold</b>!');

Answer №6

If you're looking to style Angular Bootstrap using CSS, consider the following solution:

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

You don't necessarily have to specify a parent element or class selector unless you want to limit its application. Simply copy and paste this rule for it to take effect on all sub-components.
