Describe how you would implement a Popover that displays on hover and remains visible for 2 seconds after moving the mouse away.
- Configure the 'trigger' to 'hover' and use the 'delay' option to set a 2-second delay.
- Use the 'data-trigger' attribute and set it to 'hover' with a custom JavaScript function for a 2-second delay.
- Set 'data-toggle' to 'popover' and use 'data-delay' for a 2-second delay.
- Utilize the 'data-hover' attribute and adjust the 'data-timeout' for a 2-second delay.
When implementing a Popover with Bootstrap, you can achieve a hover-triggered display with a 2-second delay by setting the 'trigger' option to 'hover' and using the 'delay' option to specify the time. This ensures that the Popover appears on hover and remains visible for the specified duration after the mouse is moved away.
