Popover is a non-modal dialog that floats around a trigger. It is used to display contextual information to the user, and should be paired with a clickable trigger element.
Popover is built on top of the Popper.js library,
and composes the Popper component.
Popover: The wrapper that provides props, state, and context to its
children.PopoverTrigger: Used to wrap the reference (or trigger) element.PopoverContent: The popover itself.PopoverHeader: The header of the popover.PopoverBody: The body of the popover.PopoverArrow: A visual arrow that points to the reference (or trigger).PopoverCloseButton: A button to close the popover.When using this component, ensure the children passed to PopoverTrigger is
focusable. Users can tab to it using their keyboard, and it can take a ref. It
is critical for accessiblity.
A11y: When Popover opens, focus is sent to
PopoverContent. When it closes, focus is returned to the trigger.
By default, the Popover doesn't render in a Portal. To make them display in a
portal, wrap the PopoverContent in a Portal
You might need to Inspect Element to see this in action. Notice that
PopoverContentis rendered as a child of<body>
By default, focus is to sent to PopoverContent when it opens. Pass the
initialFocusRef prop to send focus to a specific element instead.
If the popover contains a form, you might need to trap focus within the popover and close it when the user fills the form and hits "save".
You can leverage
react-focus-lock to trap focus
within the PopoverContent.
You can control the opening and closing of the popover by passing the isOpen,
and onClose props.
Sometimes you might need to set the returnFocusOnClose prop to false to
prevent popver from returning focus to PopoverTrigger's children.
Chakra provides access to two internal details: isOpen and onClose. Use the
render prop pattern to gain access to them.
Chakra exports all the components you need to customize the look and feel of the popover. You can change the background, arrow size, box shadow and so on.
Since popover is powered by PopperJS, you can change the placement of the
popover by passing the placement prop. See the props for the
possible placement values.
Even though you specified the placement, Popover will try to reposition itself in the event that available space at the specified placement isn't enough.
By default, the Popover component renders children of PopoverContent to the
DOM, meaning that invisible popover contents are still rendered but are hidden
by styles.
If you want to defer rendering of popover content until that Popover is
opened, you can use the isLazy prop. This is useful if your PopoverContent
needs to be extra performant, or make network calls on mount that should only
happen when the component is displayed.
When you see the word "trigger", it is referring to the
childrenofPopoverTrigger
PopoverContent. If the
initialFocusRef is set, then focus moves to the element with that ref.returnFocusOnClose to false, focus will not return.hover:PopoverContent, it'll remain visible.click:Space or Enter when focus is on the
trigger will open the popover.Esc key while the popover is open and focus is within the
PopoverContent, will close the popover. If you set closeOnEsc to false,
it will not close.PopoverContent closes the popover.
If you set closeOnBlur to false, it will not close.click, the PopoverContent element has role set to
dialog. If the trigger is set to hover, the PopoverContent has role
set to tooltip.PopoverContent has aria-labelledby set to the id of the
PopoverHeader.PopoverContent has aria-describedby set to the id of the
PopoverBody.PopoverContent has aria-hidden set to true or false depending on
the open/closed state of the popover.aria-haspopup set to true to denote that it triggers a
popover.aria-controls set to the id of the PopoverContent to
associate the popover and the trigger.aria-expanded set to true or false depending on the
open/closed state of the popover.| Name | Type | Description | Default |
