I am developing an VISITOR Adobe Interactive Form, i have Designer 8.1 and Reader 9.0 in my Windows 7 Laptop. When i checked the menu EDIT-->form properties --> Compatability, its Adobe XML form File (XDP)
When i opened this VISITOR interactive form in a browser, right clicking and checked form PROPERTIES, then i saw the "PDF Version: 1.6 (Acrobat 7.x)"
When i opened VISITOR interactive form in browswer, i saw a purple ribbon on the top of the form with a text of "Pls fill out the folowing form. You can save data typed into this form" on left corner and i can see a button HIGHLIGHT FELDS on the right corner, if i press this button, all mandatory fields on the form getting RED colored border (this is good, i want this feature)
1) Why am getting this purple riboon on the top?
To 1: That "purple ribbon" is provided by Acrobat/Reader higher than version 8, if the document has writable form fields. It does not matter whether you have the document opened in Acrobat/Reader or under the browser (as long as the Acrobat component is version 8 or higher).
To 2: Most likely, if their PDF viewer component is based on Acrobat 8 or higher.
To 3: You can't suppress or modify that "purple ribbon" from the document (one of my serious pet peeves with Acrobat, but that's another story). The user (only the user) can collapse it by clicking on the icon at the left. If you are "heavy" enough towards Adobe (many millions of dollars business per year), you may try to "persuade" them to get rid of that thingie… good luck!)
Hope this can help.
