Individual position the recaptcha and the send button in the form

[inu-web]

Is ther a possibility to define the position of the recaptcha iframe in the form
I know how top make custoim template via the template definition in view.json - but how can I define to show the recaptcha iframe and the send button in a special position in my template?
e.g template:
< div class="container" >
< div class="row" >
< div id="name" class="col-md-4" >< /div >
< div id="email" class="col-md-4" >< /div >
< div id="recaptcha" class="col-md-4" >< /div >
< /div >
< div class="row" >
< div id="send" class="col-md-12" >< /div >
< /div >
< /div >
I know that Alpaca generates bootstrap by default - but I want to implement a more complex template and this is just an example
Any hint pointing me in the correct direction is highly appreciated
