When working with notifications in React, it's important to control how toasts behave and interact with users. You have several options to fine-tune the user experience, including autoClose, pauseOnHover, draggable, and closeButton. The autoClose option sets how long a toast remains visible before closing automatically. Setting autoClose to a number (in milliseconds) determines the delay; setting it to false makes the toast persistent until the user dismisses it. The pauseOnHover option allows the toast timer to pause when the user hovers over the notification, giving them more time to read or interact. The draggable option lets users manually drag and dismiss the toast, making the notification feel more interactive. The closeButton option controls whether a close button appears on the toast, allowing for immediate dismissal.

Each of these options has its own use cases. Persistent notifications, created by setting autoClose to false, are helpful for alerts that require user action or acknowledgment, such as critical errors or confirmations. Dismissible notifications, with a visible close button, are ideal when you want users to have control over when a message disappears but don't want it to linger indefinitely. For less important or informational toasts, setting a short autoClose time and enabling pauseOnHover ensures users see the message without needing to take action. Enabling draggable makes toasts feel less intrusive, letting users move them out of the way if needed.
