Сlass input-group

Hello

Wappler has a form-group class for creating forms. But I could not find the input-group class to create composite inputs (example on the screen):

I can use this element in code because it is part of bootstrap, which is supported by Wappler. But I would like to be able to visually customize the element, also as the element with the form-group class. Maybe I just did not find it in Wappler, and it is there? Tell me please.
