Simple Use Case

The popover component will be automatically positioned relative to its nearest parent. If usePortal is set to false, then it will be positioned relative to its nearest ancestor with the CSS property: position: absolute | relative | fixed.

Properties

| Prop | Type | Description | Default | | ------------------ | ---------------------------------------------------------------------------------------------- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | ---------- | --- | | active | boolean | Determines whether the Popover is active or inactive | false | | align | 'top' | 'bottom' | 'left' | 'right' | 'center-horizontal' | 'center-vertical' | A string that determines the alignment of the popover relative to the refEl. | 'bottom' | | justify | 'start' | 'middle' | 'end' | 'fit' | A string that determines the justification of the popover relative to the refEl. Justification will be defined relative to the align prop | 'start' | | children | node | Content that will appear inside of the <Popver /> component | | | spacing | number | Specifies the amount of spacing (in pixels) between the trigger element and the content element. | 10 | | className | string | Classname to apply to popover-content container | | | adjustOnMutation | boolean | Should the Popover auto adjust its content when the DOM changes (using MutationObserver). | false | | onClick | function | Function that will be called when popover content is clicked. | | | usePortal | boolean | Will position Popover's children relative to its parent without using a Portal, if usePortal is set to false. NOTE: The parent element should be CSS position relative, fixed, or absolute if using this option. | true | | portalContainer | HTMLElement | null | Sets the container used for the popover's portal. NOTE: If using a scrollContainer make sure that the portalContainer is contained within the scrollContainer. E.g, passing the same refrence to scrollContainer and portalContainer. | | | scrollContainer | HTMLElement | null | If the popover portal has a scrollable ancestor other than the window, this prop allows passing a reference to that element to allow the portal to position properly. | | | portalClassName | string | Passes the given className to the popover's portal container if the default portal container is being used. | | | popoverZIndex | number | Sets the z-index CSS property for the popover. | | | | ... | native attributes of Portal or Fragment | Any other properties will be spread on the popover-content container | |
