For example, the dialog can be displayed when a user hovers over an item, clicks a button, or selects a value in a drop-down selection list.
例如,可以在用户将鼠标悬停在某个项目上、单击按钮或从下拉列表中选择值时显示对话框。
When the value is a non-empty list, the text in the block will be displayed once for each item in the list.
当值为非空列表时,列表中的文本则会被遍历展示。
