Tou have updated to 3.1.4 from which version ?

Yes, this should be a jQuery conflict...

I will see it, and test it.

Is menumatic a joomla extension ? Don't find it as so...

For information, in 3.1.6 zip file of iCagenda (and on your ftp) you have a file in modules/mod_iccalendar/js/function_312.js

Remove the current function/js file, and after rename function_312 in function.js

And then, after refreshing of page, can you tell me if it's working ?

I did what you asked. still the same.

Let me try another dropdown menu.

You have maximenuCK (used by Joomla.org, and developpe by Cédric, a very good and active developper!)

But, you told me it was working with 2.1.4, so, for me, to enhance my code, and do the best coding i can, it's important for all users that i can solve this problem, and edit my code to make it working for all!

So, do you have a possibility to send me your menumatic and/or template, or to test by installing the module calendar i join to this message ?

You will be able just after to go back to 3.1.6, by installing again via extension manager. (but always without uninstalling iCagenda to not lose your data !)
