Sets a value specifying the style of the combo box.
Parameters
droop_down_style
One of the combo_box_style values. The default is drop_down.
Remarks
The drop_down_style property specifies whether the list is always displayed or whether the list is displayed in a drop-down. The drop_down_style property also specifies whether the text portion can be edited. See combo_box_style for the available settings and their effects. There is no setting to always display the list and disallow entering a new value. To display a list to which no new values can be added, use a list_box control.
