Choices in Columns - Introduce a setting to specify the choice order (row/column) at the survey level

[JaneSjs]

Add an option which configures the choice layout for a survey so that it can be modified by survey creators.

          @jmar1998 Please set the following code before initialization the survey model:

Survey.settings.showItemsInOrder = "column".

  /**
   * By default checkbox and radiogroup items are ordered in rows.
   * Set it "column", and items will be ordered in columns.
   */
  showItemsInOrder: "default",

Thank you, Andrew
