Collapse

Toggle the visibility of content across your project with a few classes and our JavaScript plugins.

Example

Click the buttons below to show and hide another element via class changes:

  • .collapse hides content
  • .collapsing is applied during transitions
  • .collapse.show shows content

You can use a link with the href attribute, or a button with the data-target attribute. In both cases, the data-toggle="collapse" is required.

This is where we sit down, grab a cup of coffee and dial in the details. Understanding the task at hand and ironing out the wrinkles is a key point.

                            </div>
                          </div>

Multiple targets

A <button> or <a> can show and hide multiple elements by referencing them with a JQuery selector in its href or data-target attribute. Multiple <button> or <a> can show and hide an element if they each reference it with their href or data-target attribute
