Datalist is a list-type component used to organize and present sets of related data.

Each element in this list, known as "datalistitem," has the capability to contain various elements such as tables, inputs, images, and other components.

This component is associated with a repository defined in "repo," allowing for the direct linking of data.

This versatility allows for the creation of interactive and customizable lists that can incorporate a variety of elements based on the specific requirements of the user interface and application functionality.
