The ability to have multiple checkmarks in one box, also known as multi-select checkboxes, is a valuable feature in many applications. It allows users to select multiple options from a list, making it easier to perform tasks such as filtering data or selecting items for deletion.
Multi-select checkboxes are commonly used in web forms, spreadsheets, and other data entry applications. They can also be used to create custom interfaces for applications, such as to-do lists or project management tools.
