Oh, I see what you mean. It’s another nomenclature problem. In my head, input groups are input fields that include buttons, icons and/or labels (as per Bootstrap). However, “groups of input fields” can simply be called forms or input forms.
An organism fulfills a more involved role. E.g. an input form can take credit card info by using multiple types of advanced inputs, such as what Bootstrap calls input groups.
The language can quickly get very confusing. Thanks for pointing that out. To avoid confusion, I’m going to remove input groups from the molecule’s classification.
