Adobe Acrobat

The values in a dialog list box are set with an object that contains all of the list items. There is no difference in how this is done before the dialog is displayed, or at runtime. The "list object" can be setup and manipulated outside the dialog object, but it can only be loaded into the dropdown while the dialog is running.

For Example:

// Setup initial listvar myList = {apple:-1,pear:-1,grape:1};// Load into dropdowndialog.load({"pop1":myList}); // Modify list at some later timedelete myList["apple"];myList["banana"] = 1;// Reloaddialog.load({"pop1":myList});

Notice the use of the "dialog" object. This is only available in functions in the Dialog Literal, called when the dialog is running. For example, the "initialize" function, or any of the action functions associated with a dialog element. But you can certainly create the drop-down list object outside of the dialog literal, so that it can be manipulated before the dialog is run.
