Popovers

Planned

Popovers are containers used to display transient content such as menus, options, additional actions, and more. They visually stand out through stroke and drop shadow and float on top of the interface.

Options

Width and Height

A popover’s width and height can be customized appropriately for its context.

Show Tip

By default, popovers do not have a tip. Popovers without a tip should be used when the source has a visually distinct down state, in order to show the connection between the popover and its source. Popovers can have a tip. A tip should be used to help show the connection to its source, in cases where the source does not have a visually distinct down state.

Placement

A popover is positioned in relation to its source. The placement property values are the following: top, top left, top right, top start, top end, bottom, bottom left, bottom right, bottom start, bottom end, left, left top, left bottom, start, start top, start bottom, right, right top, right bottom, end, end top, end bottom. The default placement value is at the top.

Offset

The offset is the distance between the source and the popover edge (or the end of the tip, when there is a tip). The default value is 6 px on desktop and 8 px on mobile, but this should be adjusted depending on the perceived bounding box of the source.

Cross Offset

The cross offset is the placement offset on the cross axis (x-axis for top and bottom, y-axis for left and right). The default value is 0 px.

Container Padding

To make sure that a popover will stay within certain boundaries (e.g., a browser window) it’s possible to define a container, and a container padding value, to respect. The default value is 8 px.

Behaviors

Animation

When displaying a popover, it should animate from its source to reinforce the connection between popover and source. It fades in and slides with a subtle motion from the source.
