I have a problem on the dynamics' crm portal:

If a customer open a ticket and want to communicate with us, he have use the "add a comment" section.

The problem is, if a client write a comment too long it takes too much space on the page.

So I am trying to find an option to collapse/develop comments.

I managed to reduce the number of comments displayed per page but I do not find how to reduce the place taken by comment.

Would you know if an option exists to display part of the comment and display more via a button or other way, or would you know a scripts that allow me to implement this feature?
