I had been looking for the best method to implement tooltips feature in CRM Form log ago. I found a lot of solutions on internet but they never satisfied my requirements. Some are using of complicated java script functions, some are using their own created wizards and some are using web service to retrieve descriptions of attribute to display as tooltip on form.
Today, I found an easy way to do that. The original idea comes from Marcello Tonarelli. But, I changed a little bit on his original code.
//Original Script crmForm.all.birthdate_c.title = "Please choose date of birth"; crmForm.all.birthdate_d.title = "Please choose date of birth";
