2 Column Control
Use the 2 Column control to place two controls next to each other on a single line in the callout. As an alternative, you can instead use a table control.
The 2 column control is only available in Grid callouts.
The 2 column control is located under Basic in the control menu.
Example
In the section of the callout shown below, three 2 column controls were used to ensure that each input field is presented on the same line as its label.
