I am working on a site setup by someone else.

The site is setup so that, after you login, you can add a company, and edit a company, to the database.

One field has text below it about the origins of the number...my client wants this entire edit screen to have a better layout..one way I could do this would be to hide this information, and allow it to appear upon a mouse click.

If I go to

» Administration » Structure » Content types » Company » Manage fields

I can see the text in a field (help text); I kind of want to add a button and then load the text onclick...can I add jQuery or javascript to this field?

I'm realizing this is a basic question; but I appreciate your help.
