Popup Column Picker
You can easily implement a column-picker UI by using the grid's columns property, a ListBox control, and C1 MVC's showPopup and hidePopup methods.
For example, the grid below loads with an auto-generated set of columns. Click the gear icon at the top-left cell to show a ListBox where you can select the columns you want to display.
