Not all forms are fillable. Sometimes form creators don’t convert their PDFs to interactive fillable forms. Or, they intentionally design a form that you must print and fill in by hand. These non-interactive forms are called flat forms.
The purple message bar indicates that the form is fillable. Depending on how the form was created, it could be “interactive” or “flat”.
Interactive form
An interactive form contains fields that you can select or fill in. You can turn on the Auto-Complete option to help you fill in forms more quickly.
Flat form with Add Text Comment tool
A flat form does not have interactive fields. However, if available, you can use the Add Text Comment (Typewriter) tool to type over blank form fields. You can add text anywhere on the form, not only within specific boxes.

A. Interactive forms highlight where you should type B. Forms with the Add Text Comment tool let you add text anywhere on the form
Note:
The purple bar displays only if the creator of the form enabled it.
Forms that display the Add Text Comment tool, let you add text anywhere on the form. If you don’t see the Add Text Comment tool palette as shown below, look for the tool in Comment > Annotations or Sign > I Need To Sign.

Note:
The Add Text Comment tool is available only if the creator of the form enabled it.
A yellow message bar may appear when you open a form in Reader. Protected View limits what you can do in a PDF to protect your computer from potentially malicious content. If you trust the source of the file, click Enable All Features. Once enabled, you can look for the purple message bar or Typewriter tool.

If you don’t see a purple bar across the top or the Typewriter tool, your form is not fillable in Reader. You must print the form and fill it in by hand.

Patti Sokol, of Sokol Consulting, created two sample forms to show the differences between a flat form and an interactive form. Click here to see a flat form. Notice that you cannot type in the fields of a flat form. Click here to see an interactive form. You can highlight the fields and type in them.
Be sure to read the information in the top text box of each sample form. Then move your cursor over the fields to see what actions are available. You can also print and save the forms to your computer.
An interactive fillable form contains fields that you can select or fill in. You can turn on the Auto-Complete option to help you fill in forms more quickly.
In an interactive form, the pointer changes to a different icon, depending the field. For example, the Hand tool changes to an I-beam
when you can type text into the form field.

The Auto-Complete feature stores entries that you type in interactive form fields. Auto-Complete then suggests or even automatically enters responses that match your typing in other form fields. The suggestions appear in a pop-up menu, from which you can select a match.
The Auto-Complete feature is off by default, so you must enable it in the Forms preferences if you want to use it.
If the form creator enabled the Add Text Comment tool, use that tool to fill out flat forms. The text you add with the Add Text Comment tool appears in the Comments List (Comment > Comments List).
Not all forms can be saved. Completed forms can be saved
only if the author of the form allows it. If the PDF author has
enabled local saving, click the disk icon in
the toolbar at the upper left of the window or in the floating toolbar if
viewing the form on the web. Then rename the file and save the form
with your information.


When you open a form in Adobe Reader, you can view the usage rights in the notification bar above the form. Contact the author of the form to change your usage rights.
In some workflows, individuals submit filled-in forms as data-only files in a format such as FDF or XML. In Reader, you can import the data to view it in the context of the complete PDF:
