Hello,
I am trying to create a feature that adds additional form inputs after clicking a button. I am using this tutorial: https://www.chronoengine.com/faqs/58-cfv4/cfv4-elements-and-html/2700-how-can-i-have-a-button-to-add-more-form-inputs.html. I have done everything like in the article, but a JavaScript added in Load JS action doesn't work. When I test my form I see all 5 pairs of input and 4 buttons immediately.
Using a web inspector i see an error: "window.addEvent is not a function"
What am I doing wrong?
Thank you in advance for your help.

Hi mieszko,

That is a CFv4 tutorial using the MooTools JavaScript library which is no longer supported in Joomla! 3.

ChronoForms v5 has both the ability to hide/show elements and to add copies of elements built in. What exactly do you need to do?

I want to have a pair of form inputs and be able to add another pair by clicking a button. Of course up to a limit. Could you tell me where I can find it in new chronoforms?

Thank you Bob!
This is exactly what I meant. But is there any option to set maximum number of added inputs? I cannot see it in multiplier settings.

Hi mieszko,

Not built-in though you can do it with JavaScript.

If the maximum number is fairly small - say five or ten - then you could add them all to the form and hide all but the first. You can then use a button to un-hide the next one, or a drop-down to un-hide a fixed number.

Thank you for your help Bob.
I have another problem with saving data from multiplier to database. I've done everything like in this FAQ: http://www.chronoengine.com/faqs/70-cfv5/5245-how-can-i-use-the-multiplier-in-cfv5.html but it still doesn't work. I have a warning: "Warning: Illegal string offset 'id' in /home/(...)/db_save/db_save.php on line 102".
I ma attaching some screenshots of my form settings:
