# Multiselect dropdown list

The Multi-Select Dropdown List allows users to select multiple options from a collapsible list in a compact interface. Each option is presented with a checkbox, and a "Select all" option can be included for quick selection or deselection of all items. Selected values are displayed in the dropdown header, making it easy to review and modify choices without leaving the current view. This widget is ideal for filtering, bulk actions, or any scenario where multiple selections are required.
