I am trying to create a custom template, part of which I am trying to edit the template of questions components (not question.pstpl) such as QUESTION_HELP, QUESTION_VALID_MESSAGE, and most importantly ANSWER (edit the view of radio list, checkboxes and so). However I can't find any template file regarding those.
Any ideas? as the other option would be using javascript and css to override such options.

There are no templates for these variables. CSS and Javascript are the most common ways to manipulate the output to your own needs. Modifiying PHP code is only suitable if no further updates are an option (not recommended). LS 3.0 will offering some improvements in templates and question styling. But personally I don't expect anything for productive use in 2017.

Appreciate your timely response. looking forward to the new updates then.

As of version 2.5, you can create template-specific custom views for questions and some of their incorporated elements - manual.limesurvey.org/The_template_edito...ws_.28version_2.5.29

Thanks Tony, I always forget about that feature. Are you using that approach in productive surveys?

Ah! you're a life saver! Would've hated fixing the view in the client-side!

Yeah, I quite often remove a lot of the Bootstrap wrapping elements among other client-specific modifications.
