Add url to the Description of a SharePoint Column

If you want to add a url to the Description of a SharePoint Column, this cannot be done by adding HTML tags in the Description field of the Additional Column Settings of a SharePoint Column. HTML tags added in the Description of a column are rendered in plain text, so that is not an option. You could achieve this though by use of the Content Editor Web Part and some JavaScript. In next example, I have create an Issue Tracking SharePoint List. In this list, I have a Lookup column called Contact, which points to a Contacts SharePoint List, located in the same site, and at the same level as my Issue Tracking List. I want to add a hyperlink in the description of my Contact Lookup column of my Issue Tracking list to the NewForm.aspx page of my Contacts list to make it more user-friendly for end-users to find where they can add values for that Lookup column.
