Popover

Introduction

The Popover component displays floating content in relation to a target. Popovers appear either at the top, bottom, left or right of their target. The preferred and default side is the bottom. Popovers use smart positioning if there is not enough space.

Implementation details

The Popover uses the Positioner from Evergreen to handle the positioning logic. Internally the Popover will make sure the Popover is positioned within the viewport. This means that sometimes the Popover flips — or the Popover might move slightly to the left or right.

When creating a Popover, you must specify both:

• Its content, by setting the content prop, and
• Its target, as a single child element or a function

When you pass a function to the content prop you will be able to close the popover inside of the content.

Popovers Close On

• Outside click
• Escape key
• The close function being called (advanced)

Focus management with

When opening the Popover when bringFocusInside is true, focus will be brought inside the Popover by looking for elements with [autofocus] first, [tabindex] second and button last.

When passing a node as the Popover children, the Popover will handle focus management automatically when closing the Popover. When closing, it will return back focus on the target if nothing else has focus.

Trigger Popover
<Popover
  bringFocusInside
  content={
    <Pane
      width={320}
      height={320}
      paddingX={40}
      display="flex"
      alignItems="center"
      justifyContent="center"
      flexDirection="column"
    >
      <TextInput autoFocus width="100%" />
    </Pane>
