Transitions

Bootstrap includes a few general use CSS transitions that can be applied to a number of components. React Bootstrap, bundles them up into a few composable <Transition> components from react-transition-group, a commonly used animation wrapper for React.

Encapsulating animations into components has the added benefit of making them more broadly useful, as well as portable for using in other libraries. All React-bootstrap components that can be animated, support pluggable <Transition> components.

Collapse

Basic Example

Add a collapse toggle animation to an element or component.

Smooth animations

If you're noticing choppy animations, and the component that's being collapsed has non-zero margin or padding, try wrapping the contents of your <Collapse> inside a node with no margin or padding, like the <div> in the example below. This will allow the height to be computed properly, so the animation can proceed smoothly.

Horizontal

Add a collapse toggle animation to an element or component to transition the width instead of height.
