Identify if CPQ is open in Laptop, Tablet or Mobile Browser

Summary:

Need to hide certain inputs based on where the Oracle CPQ website has been opened (Laptop,Tablet or Mobile).

How can we identify in run time where the website is opened?

Content (required):

Checking on the support web and google. Found that we can identify the browser by  navigator.userAgent.match(/iPad/i)

Is there any better way of identifying this in CPQ? Are there any security concerns if we use userAgent?
