This is a quick post to test the issue when using numbers as IDs as brought up in this thread:
https://wordpress.org/support/topic/multiple-titles-open-when-clicking-on-one/
To recreate this we will use two collapse elements with the ID’s of 1,2,3, 11, 12 and 13.
Trigger One
Content for ID one
Trigger Two
Content for ID two
Trigger Three
Content for ID three
…Trigger Eleven
Content for ID eleven
Trigger Twelve
Content for ID twelve
Trigger Thirteen
Content for ID thirteen
The issue is the toggle selectors where using the following jQuery selector:
jQuery('[id^=target][id$='+id+']')As of collapse-o-matic version 1.7.9 the selector is a more exact:
jQuery('#target-'+id)
