By default disable Traits, On previous change in traits Enable next traits.

@HarshOB Did you check already the wiki about Traits? I explain there how to add checkbox inputs and how to react to their changes. If it's not clear can you point me out what should I add?

Here I explain again with a screenshot. You can see that there are two text fields under one checkbox. So, when I clicked on checkbox/ check that checkbox then that two input fields will be enabled(I want it to disable when it loads for the first time).

No, it's not something you can do with a built-in trait, but you can define your own type (which can even include all your inputs) by extending the default one
