The data-toggle attributes in Twitter Bootstrap

Question

What does data-toggle attributes do in Twitter Bootstrap? I couldn\'t find an answer in Bootstrap API.

I have seen a similar question before as well, li

Answer 1

The presence of this data-attribute tells Bootstrap to switch between visual or a logical states of another element on user interaction.

It is used to show modals, tab content, tooltips and popover menus as well as setting a pressed-state for a toggle-button. It is used in multiple ways without a clear documentation.
