# useItemOverflow

> Responsive and dynamically calculates the number of items that can fit within a container without overflowing, while accounting for a "+X" overflow indicator. It automatically adjusts to container resizes and provides utilities to render responsive lists (e.g., tags, avatars, or badges) that gracefully handle overflow.
