Sizing

The theme offers styles to display "small" and "large" Select2 widgets in Bootstrap Input Groups with Bootstrap Control Sizing classes applied (e. g. Select2 in .input-group.input-group-sm or .input-group.input-group-lg). You may also apply the Bootstrap Control Sizing classes directly to the .select2-container to alter its appearance.

Why are some Select2's not scaled?

While .select2-container--bootstrap.input-sm and .select2-container--bootstrap.input-lg work as advertised, Select2 4 currently does not offer copying CSS classes from the original <select> element in an easy way like version 3.x did. So we do did it manually in this example.
