List Listbox
Single selection
A Listbox List can be leveraged to let users perform a single selection, for example in a custom dropdown field. You can choose whether to show the selection checkmarks at the beginning or at the end of each List Item, and you can initialize the single selection with a prefilled value. Also, you can disable some of the options: the respective List Item will still be focusable, but a tooltip can be displayed on hover and focus and leveraged to provide useful details as to why that item is not selectable.
Multiple selection
A Listbox List can be leveraged to let users perform a multiple selection, for example in a custom dropdown field. You can choose whether to show the selection checkmarks at the beginning or at the end of each List Item, and you can initialize the multiple selection with a prefilled value. Also, you can disable some of the options: the respective List Item will still be focusable, but a tooltip can be displayed on hover and focus and leveraged to provide useful details as to why that item is not selectable.
