Regarding sorting Lists, which of the following options is correct?

The assertion that other widgets should be used to allow the end-user to define the sort criteria is correct because it highlights the limitation of the built-in functionality of lists in a reactive web application. Lists do not inherently include options for sorting by user-defined criteria without additional interface components.

In a typical user interface scenario, allowing users to select their sorting preferences enhances usability. This can be achieved through various widgets like dropdowns, sliders, or checkboxes, which serve as controls for users to specify how they want the displayed list to be sorted. By employing these widgets, developers can capture user input and dynamically adjust the sorting of list items based on the given criteria. This approach illustrates the importance of keeping the user in control of their experience, making applications more interactive and user-friendly.

The other options do not accurately reflect the capabilities available with lists in this context. For instance, the absence of a built-in On Sort event indicates that sorting functionality must be customized and cannot be executed through a predetermined event triggered by the list itself. Furthermore, the notion that sort clauses cannot be changed dynamically contradicts the flexibility usually allowed in modern application frameworks, where developers are often empowered to manipulate such settings in response to user actions.
