Popup ListBox Dialog
The xDialog Popup ListBox dialog as an alternative to the AMS ListBox or
ComboBox object. It can be used for simple lists with a few items or large lists
with thousands of items. Items can be hard coded in, loaded from a Lua table, a
text file or an SQLite database.
Using a lot of ComboBox objects with a large amount of items on one page can
really slow down page loads because you have to load the data into each ComboBox
when the page loads. With the xDialog popup ListBox, you only load the list when
it is needed.
You can set the title, the width and the height. See the example code below.

to see it in action.
These examples assume that the xDialog functions have been added
to the Global functions. You can easily do this using the Add Code button
on the Script Editor.
Example 1
-- Create a lua table and add some items to display in the listbox
tItems = {}
tItems[1] = "Red"
tItems[2] = "Green"
tItems[3] = "Blue"
tItems[4] = "Orange"
tItems[5] = "Yellow"
tItems[6] = "Pink"
-- Combine all the items into a string using "|" as a delimiter.
-- You must add a "|" to the end of the string
sItems = Table.Concat(tItems, "|", 1, TABLE_ALL).."|"
-- Show the listbox and pass it the list of items to display
Item = xDialog.Show_ListBox("Please choose an item", sItems, 130, 125)
-- If an item was selected, then add it to the input field.
if Item ~= "CANCEL" then
Input.SetText("Input1", Item)
end

Example 2
-- Create a lua table and add 500 items to it using a For Loop, to display in the listbox
tItems = {}
for n=1, 500 do
tItems[n] = "Item number "..n
end
-- Combine all the items into a string using "|" as a delimiter.
-- You must add a "|" to the end of the string
sItems = Table.Concat(tItems, "|", 1, TABLE_ALL).."|"
-- Show the listbox and pass it the list of items to display
Item = xDialog.Show_ListBox("Please choose an item", sItems, 130, 125)
-- If an item was selected, then add it to the input field.
if Item ~= "CANCEL" then
Input.SetText("Input1", Item)
end
