Once you've created at least one question group, you'll be able to add questions to your survey. If you've just created a Question Group, (and if you have more than one question group, once you select a question group) you'll see the Question toolbar:
Click on the Add New Question icon to add a question.
An icon bar will be displayed giving you full control (including preview ability and logic branching):
Hover over each icon for a tool tip. The red/yellow/green branching icon is used to build branching logic into your questions -- this lets you set rules to determine if a question shoud be displayed, based on responses to previous question(s).
A question is comprised of:
- A response code
- The question text (for example: What is your favourite colour?)
- Help text if you wish to provide any.
- Question Type (see full descriptions on the LimeSurvey wiki) -- the system will provide you with preview images of each question type to help you select the appropriate type.
You also have the option of viewing Advanced Settings for each question. This gives you extensive control over each question and its behaviour.
