Question: I had enabled a views accordion for a field in view. On displaying it in a page its not working and I got an error "$(...).accordion is not a function". Can any one help me in solving this?

Answer: 
Install the [jQuery Update](https://www.drupal.org/project/jquery_update) module and set jQuery of your website to `1.7+`.
It seems like your jQuery libraries are creating conflict. Try to use 'jQuery' instead of '$'.
Else you can use a simple line of code to avoid jQuery library conflict.
