Need to edit current drop down lists on form

[MULCACA]

I have a form that I need to edit that already includes drop down lists. This form is saved as Adobde Dynamic XML form. I used to be able to see contents of drop down list in the Library section and just add to or edit from there but this option is no longer available?

Got my answer on youtube - simply click on Window and Select Object and then the library of info reappears for editing.
