I'm using LimeSurvey Versión 2.05+ Build 140109, and I have imported template, that do no show the tipical radio buttons (in fact, show the same text that is created to specifiy the header of the table....i attach a picture to show it).
I suppose there is a way to create a symbol or a special character for each non-selected and selected option (full and empty radio button, empty and checked square, or similar).
