In the Tree block of the ribbon, select the Dropdown type and create the item as child of your ribbon's blocks. Here you can give the select button a name and an icon. Save the changes.
Next, to populate the control, you can add Items to it as children. Each will be given a label, a code to identify it, an icon and a related menu function. If you have multiple items in a select control, you can specify their order through the Sequence field.
If you open the screen containing the ribbon, you can use the select button to launch the respective functions of the select options. The select button can be hidden from the ribbon or shown again programatically.
