Usability of Radio button css component


Hello all,

I am currently implementing the ionic radio button list.
I’m afraid that it isn’t obvious to the user that it is a radio button group
Especially when you have list without a radio button checked. That way you will just have a list of items, no way of knowing you can actually select one. The moment an item is checked things become more clear, but what if you want to force the user to make a decision instead of pre selecting an item beforehand.


What is your opinion about this, or am I missing something obvious ?
