Background
We need to implement the Popover component in Codex.
The need for this component stems from having an existing Popover in OOUI and conversation from the Tooltip task.
Description
Popover component provides a localized container based on a trigger to provide long for information, layouts, and interactive elements.
User stories
- As a user, I need additional space to provide information or interactivity based on an existing element on the page.
Potential use cases
 | Wikidata Query Builder uses the Popover component from the WiKit design system (in deprecation). |
