Loops
Metaforms supports a wide range of Loops in your surveys.
Let's take a look at all of them:
Normal loop which shows some questions for brand list and the brand name is piped in those questions without any condition.
Loop which shows some questions for the brand list and the brand name is piped in those questions and the loop is run only for the options selected in a previous multi select question. Base checkbox question.  Loop with two questions which are iterated for the option selected in the base checkbox question.  
Loop with randomised iterations where one of the iterations is anchored. 
Loop with iterations randomised based on the question outside of the loop.
Base question from which the order of the loop will be controlled based on how the options are randomised in this question 
Loop for which the randomisation order is maintained from the base question 
Loop with multiple loop variable to pipe the text.
Example - Knowledge and Tagline Fit (Publisher + Tagline Pairs)
 
Loop with condition some loop iterations only.
Before loop there are few radio questions as below.  
Some iterations of the loop with condition based on previous question.
Question inside Loop with conditions on the options based on the loop iteration implementing this logic using looprows attribute in rows. Example: Timings are displayed based on the type of the book    
Loop iteration shown based on the least fill logic of previous checkbox question.
  Along with the main loop, below are the nested loop where options are shown based on the which iteration is currently running in the outer loop and inner loop.  
Nested loop with the below logic implemented
Multi-select checkbox question with different types of vehicles.
Based on previous multi-select checkbox question, we have main loop which is asked based on the selected vehicles type. 
Inside the main loop, there is a numeric question where the vehicle type appears in the question text, and different vehicle models are shown as options based on the vehicle types selected in the previous checkbox question.
Inside the main loop there is inner loop based on the vehicle models, which is shown if vehicle model has value more then zero at the previous number question.
For inner loop there are number and radio question, where value from previous number question and vehicle model text are shown in the question text.
