Class
An item that can be used in a Dialog and takes up the full width of
the dialog, but can be populated with an array of inner items, that will be
arranged in that row. This corresponds to the "bar" type of body component
in a TinyMCE dialog. By default, all columns in the row take up the same
amount of space, but you can make one larger if you modify the style of the
element after it has been placed into the DOM, setting one of the
sub-elements to have width: 100%.
Construct a dialog row.
Object
<repeatable>an array of dialog items (e.g., AlertItem or ButtonItem) to place into this row
