Form-group horizontal

I want to create a form with form-groups running top-down and label & input being horizontal… but it seems impossible to achieve:

  <div class="form-group row">
   <label class="col-form-label">Input 1</label>
   <input type="number" class="form-control" />

I read I should add a row class which is for horizontal forms… but no effect.

Any idea how to get it working?

Did you try with input groups
here is an example
