Use this config option to change the default widget type groups shown in the tile view (for example, Multiple Choice, Fill in the Blanks (Cloze)).
Supply an array with objects defining a group. Each group needs a unique identifier and a name.
If you want to override the name and/or icon for the default groups, find the reference (look for the data-groupreference attribute in the DOM) and specify a new name and/or icon. Any new references will be added as additional groups in the tile view.
