I do not know how your HTML is, but you can do something like this:
See that there are span elements with "type- {input_type}" classes involving each type of input, along with their labels. I use these classes to do the following using JQuery:
What the code does is to select elements of type span that do not have the class "type- {selective_type}" (using the: not selector, see more about it here ) and hide them, as well as displaying the span element with the selected class, if it has been previously hidden.
