You are free to add desired options to the Theme-Options.
In the config.xml of your theme you find the section <options>
Code:
<!-- You can add here any option you want. It will be available in twig file via aSurveyInfo.options.youroptionname -->
<options>
<hideprivacyinfo type="buttons" category="Simple options" width="4" title="Hide privacy info" options="on|off" optionlabels="Yes|No">off</hideprivacyinfo>
<container type="buttons" category="Simple options" width="4" title="Survey container" options="on|off" optionlabels="Yes|No">on</container>
.....
As example I show the "headerbackgroundcolor"
config.xml:
then you get this in the "theme options"
and in the twig file you see how it is implemented
This way you can offer your uses several options to adapt in their surveys.
