# TCustomComboBox.DropDownCount

The maximum number of Items visible in the drop-down list for the control.

## Declaration

Source position: stdctrls.pp line 433

`public property TCustomComboBox.DropDownCount : Integer read FDropDownCount write SetDropDownCount default 8;`

## Description

DropDownCount is an Integer property which specifies the maximum number of values from Items that can be displayed in the drop-down list for the control. Setting a new value for the property causes the widgetset class to be notified using its SetDropDownCount method when a handle has been allocated for the control.

DropDownCount is used (along with the item count and ItemHeight) in the AdjustDropDown method to set the minimum dimensions for the drop-down list.

The default value for the property is 8.

Remark: | For the macOS Carbon and GTK2 widgetsets, changing the value in DropDownCount does not affect the control. This attribute is determined by the native control.
