This is not a lss export, it's a lsq export.
Please provide lss.

There are no subquestions and no answer options.
How do you expect it to work?

And there is no script.

As I wrote before:
You got a full sample survey (with more option than you need) here
[url] forums.limesurvey.org/index.php/forum/de...swer?start=48#233998 [/url]

And here you find a full sample for the "apple-banana"
[url] forums.limesurvey.org/index.php/forum/ca...dels?start=24#170368 [/url]

Why don't you just import the sample to study it and to adapt it?

May look like this
 
or with the buttons at the top
 


And a last word why we ask for lss exports.

lsq (questions) and lsg (groups) exports are language sensitive.
You can't import such an export into a survey with a different base language.
We have to create a new survey, guessing the base language of your export to be able to import it.
Furthermore these exports don't include survey wide settings that may be important.
So, please, ease the life of us volunteers.

Thank you for your patience! 
I have redone the same exercise "banana/call" to practice with adapting it to my case. but the problem is that the choice bar does not appear? do you have any idea why? I copied the CODE ! proposed here  forums.limesurvey.org/index.php/forum/ca...oice-models?start=24

Thanks to your help :)
I finally gave up trying to create my cards on LimeSurvey because the final result was not as beautiful as my original cards. So I created my cards on Canva and imported them directly. 

Now I have a questions about the design of my DCE, I have 18 cards of choice divided into 3 blocks. Each of my respondents has to make 6 choices (cards): 
- How can this be done, i.e. each respondent has access to all 6 cards?
- Is it also possible that the respondents to my survey are randomly distributed over the 3 blocks?

Thank you again for your help and your time.

Of course
you are free to create the HTML table. Do whatever you want.
In my last project I used the whole bootstrap stuff.
The "apple - banana" is only a skeleton to show the general way. 


But the design of the experiment is something else.
What exactly means.

I have 18 cards of choice divided into 3 blocks. Each of my respondents has to make 6 choices (cards): 

You have 3 blocks. each one contains 6 cards.
Now what about your respondents? Each one answers one block? I don't think so.
Your respondents answer 6 cards randomly out of the 18?
Your respondents answer 2 cards out of each block?

Please, explain.
Best you show an example.

Yes, I have 3 blocks with 6 choice cards each.

I am going to import the 18 cards into LimeSurvey, I want to know if I can add conditions so that each of my respondents answers to one block (6 cards).
For example, the first respondent in my DCE responds to the 6 choices in block 1 and the second respondent responds to the 6 choices in block 2 and the third respondent responds to the 6 choices in block 3 and so on.

Overall, I want to have the same number of respondents per block, i.e. if I have for example 100 respondents at the end I want 33 individuals to have answered the choices for block 1, 33 for block 2 and 34 for block 3.

I hope my request is clear to you !
Many thanks.

You will have to randomize the blocks then. However, chance is never perfect, so you most probably won't get a real even distribution, especially not with such a small sample.

You most probably will have to adjust towards the end of your field time.

If you would know German, there is some pretty good information about all this in one of Joffm's tutorials that you can find in the German forum as PDF files.
