If there is too much data to be displayed in the box, then scroll bars will be displayed. Simply use the scroll bars to find the value. A combo box is like a list box, but takes up less room. It looks like a text box, but has a drop-down arrow to the right, that can be clicked to display more values in the text box. The list in a combo or list box consists of rows of data.
Rows can have one or more columns, which can appear with or without headings.
Open a form in Design view. Click the Control Wizards tool in the toolbox if it's pressed in. This turns off the wizard. In the toolbox, click the Combo or List Box button. On the form, drag and drop where you want to place it.
