I have several survey groups. How can I set that, my participants first see these categories after their Login, then select a desired group and consequently select a survey which belongs to the chosen survey-group.
First of all: Limesurvey does not have the availability of a login for survey takers. So you might have to program this outside of Limesurvey and then link to the respective surveys.
I answer at the LimeSurvey forum in my spare time, I'm not a LimeSurvey GmbH employee.
