Why Does SfDropDownBase.AddItem take an IEnumerable as a parameter?

Question

Hi, just in case I am missing something, can you please let me know why the function SfDropDownBase.AddItem (singular) requires an IEnumerable items (plural) as a parameter please?

public Task AddItem(IEnumerable<T> items, int? itemIndex = null);

The function is named "AddItem" (which indicates adding a single item) yet the input parameter is called "items" which is plural / indicates multiple items to be added?

Hi Jeyanth,If I create a list with six items, and pass this into the function "addItem", have I added a single item, or have I added multiple items?
