By default, when the user clicks the C1DropDown control's drop-down arrow at run-time the color picker will appear below the control, and, if that is not possible, above the control. However, you can customize where you would like the color picker to appear by setting the DropDownDirection property.

You can set the DropDownDirection property to one of the following options:

 

Event	Description
BelowOrAbove (default)	Tries to open the drop-down box below the header. If it is not possible tries to open above it.
AboveOrBelow	Tries to open the drop-down box above the header. If it is not possible tries to open below it.
ForceBelow	Forces the drop-down box to open below the header.
ForceAbove	Forces the drop-down box to open above the header.
