While working with a web application, the user sometimes needs to receive feedback messages, for example, about successful saving/updating of data, completing some processes, or an error that occurred.

Block to display messages in AppMaster

With this block, you can customize the title and text of the message, the type of message, choose where to place the message on the page, and the length of time for which the message will be displayed. You can manually or dynamically set a value for each of these parameters by creating your custom logic.
