One solution that I use is a home-made popup list. It takes 10 minutes of
set-up but once you have it in place you can call this function on mouseup
anywhere you want it. The basic idea is to have a separate popup button in
your stack (invisible) that is loaded on the fly then shown with a "popup
btn xxx" command. See below.

Can be used for right-click contextual menus too. Anywhere.

function popChoose
   -- popChoose() is the equivalent of the "answer" command, but for a
pop-up list
   -- pops up a list of options, returns the option chosen by the user,
   --    if no option chosen, exits to top
   -- you must have a button "contextualMenu"
   --    button style = menu, menumode = popup, name = "contextualMenu"
   --    the button should be placed in your mainstack or a library stack
   --    button can be made invisible when you're done, if you like
   -- the button script needs only one handler:
   --    on menupick what
   --       set the uSelection of me to what
   --    end menupick
   -- paste this handler into a suitable stack script, so it's available
anywhere
   --    could be the same stack the button is in, but that's not necessary
   -- enter the short name of the stack containing the button
   --    into the constant declaration below

   -- popChoose() can accept a cr-delimited list of choices
   --    or a comma-delimited list
   -- eg: put "parsley" & cr & "sage" & cr & "rosemary" into choiceList
   --     put popChoose(choiceList) into userChoice
   -- or: put popChoose(choice1,choice2,choice3) into userChoice
   -- or: put popChoose("parsley","sage","rosemary","-","thyme") \
      --           into userChoice
   -- if you need the line number of the chosen item, check the dialogdata
   --    after calling popChoose()

   constant popChooseStackName = "yourLibraryStack"

   repeat with n = 1 to paramcount()
      put param(n) & cr after tList
   end repeat
   delete char -1 of tList
   put empty into u
   set the uSelection of btn "contextualMenu" of stack popChooseStackName to
empty
   put tList into btn "contextualMenu" of stack popChooseStackName
   popup btn "contextualMenu" of stack popChooseStackName
   put the menuhistory of btn "contextualMenu" of stack popChooseStackName \
         into lineNbr
   put the uSelection of btn "contextualMenu" of stack popChooseStackName
into u
   set the uSelection of btn "contextualMenu" of stack popChooseStackName to
empty
   put empty into btn "contextualMenu" of stack popChooseStackName
   -- belt and suspenders, don't leave contents hanging around
   select empty
   if u = empty then
      exit to top
      -- ie, mouseRelease, no action
   end if
   set the dialogdata to lineNbr
   return u
end popChoose
