combo box

基本解釋

For example, data can be represented as standard text, a combo box, or a check box.
例如，數(shù)據(jù)可以代表一個標準的文本，一個組合框，或者一個復選框。
If the style is a combo box, as previously in Figure 4, then its values must also be added.
如果這個類型是一個組合框，如前面的圖 4所示，那么它的值也必須被添加。
With a standard drop-down list, the user is limited to choices in the list, but with a combo box, the user can enter a value that is not in the list.
通過標準的下拉列表，用戶只能夠選擇列表中的選項，但是如果使用組合框，那么用戶就能夠輸入一個列表之外的值。
