In Google Apps Script, menus, dialogs, and sidebars are user interface elements that can be used to enhance the functionality of a Google Sheets, Docs, or Forms application.
Menus are a great way to group related actions or commands in an organized manner. They appear at the top of the document, and when clicked, they display a list of actions. The actions can be custom functions or built-in commands. For example, you can create a custom menu that contains a set of functions to automate repetitive tasks, such as formatting data or inserting values.
Dialogs are pop-up windows that display information, request user input, or provide feedback. They can be created using HTML and CSS, including buttons, text boxes, drop-down lists, and other elements. Dialogs are particularly useful when you provide users additional context or guidance about a specific task or process. For example, you can create a dialog to prompt users to enter specific information before running a function.
Sidebars are similar to dialogs in that they provide additional context or functionality, but they are displayed on the side of the screen rather than as a pop-up window. They can also be created using HTML and CSS, and can include interactive elements such as buttons and forms. Sidebars are useful when you want to provide users with ongoing access to tools or information needed to complete a task. For example, you can create a sidebar that displays a list of frequently used functions or a form for users to enter data.
Overall, menus, dialogs, and sidebars are great ways to extend the functionality of your Google Sheets, Docs, or Forms application and provide a better user experience for your users.
