Hi everyone,

I'd like to use limesurvey as a tool for respondents selecting optional items from an item list. I managed to build a survey in which there are 3 items, all of them are selectable through a "yes/no" question type. I'd like limesurvey to only allow the user to select as many as 2 items from 3 (Later there he's allowed to select maybe 25 items from a list of 40 items or so).
What would also be needed in addition is that the maximum of selectable items is defined through a token value, so that the definition of the max-value will be through a value stored in the token table. The purpose of that is that one can assign each potential user a unique max-value.

How could that be achieved? (if it is possible at all?)

One remark: I know an easier way would perhaps be a multiple choice question, however, the task is a bit more complicated. once the user selects one item by clicking "yes", a dropdown-field appears in which he or she can select the exact wording of that item. for achieving an appropriate layout, I used a javascript code which I found in some of the workarounds sections of limesurvey (or in an example lss file, I can't remember exactly).

At the moment the layout of the questions looks like attached...


thanks in advance,

As we have no clue what code you used to achieve that layout and functionality, it's hard to give constructive advice.

Having said that, I imagine you will need to put a listener on the radios and disable the unchecked ones when a maximum is reached. Something like this (untested):

Hi, looks good, I will test it and write about the success. If it fails I will send my code in the next reply.
thank you very much for your answer!

Hello again, I tested your code and it works perfect - wow! Thank you so much!
