May use ComboBox, it can be edit like editbox, has .Text field to get edit content, and autoComplete functionality build in.
eg.
Code:

local inet = getInternet()
cns = cns or inet.getURL[[https://gist.githubusercontent.com/kalinchernev/486393efcca01623b18d/raw/daa24c9fea66afb7d68f8d69f0c4b8eeb9406e83/countries]]
inet.Destroy()

local frm = createForm(false)
frm.OnClose = function()return caFree end
frm.Width,frm.Height,frm.Name = 600,200,"TEST_TEST"

frm.ChildSizing.Layout = "cclLeftToRightThenTopToBottom"

local edt = createEdit(frm)
edt.Text ="...for interaction..."

local cmb = createComboBox(frm)

cmb.AutoComplete, cmb.AutoDropDown = true, true
cmb.AutoCompleteText = "[cbactEnabled,cbactEndOfLineComplete,cbactSearchAscending]"
-- all option -> "[cbactEnabled,cbactEndOfLineComplete,cbactRetainPrefixCase,cbactSearchCaseSensitive,cbactSearchAscending]"
cmb.Items.Text = cns   --   set autoComplete list here, should be sorted
cmb.onEditingDone = function(me)
  edt.Text = me.Text
end

frm.Show()

panraven, i think better use tables and listbox.
first table contain all string items, then copy some items with paremeter key got from user input on edit box to second table. Next show filtered items to listbox.

I try to do it now, but my problem is copy items from 1st table to 2nd table with parameter key.

Code:
main_tab = {
"IDname = Albanian",
"IDname = Amazone",
"IDname = Baltimore",
"IDname = Bronx",
"IDname = California",
"IDname = Chile",
"IDname = Detroit"
}


for editbox :

Code:
local get_text = UDF1.CEEdit1.Text

if get_text == nil or get_text == "" then
 return
 else
 first_letter = string.sub(get_text, 1, 1)
 print(first_letter)
end


so, first_letter is the parameter key.
Now, I need get all items from main_table which meets key parameters obtained from the editbox and add those items to second table.
Last is add listbox item from second table item.

EDIT 1 : something like this (unfinish)

Code:
fm = createForm()
fm.width = 200
fm.height = 200
fm.caption = "TEST"

edt = createEdit(fm)
edt.left = 10
edt.top = 10
edt.width = 180

list = createListBox(fm)
list.top = edt.top + edt.height + 10
list.width = 180
list.height = 160
list.visible = false

main_tab = {
"Albanian",
"Amazone",
"Baltimore",
"Bronx",
"California",
"Chile",
"Detroit"
}

function tablelength(T)
  local count = 0
  for _ in pairs(T) do count = count + 1 end
  return count
end


function lbCheck()
 local get_text = edt.Text
 if get_text == nil or get_text == "" then
  list.clear()
  list.visible = false
  else
  filter_letter = string.sub(get_text, 1, 1)
--  variable1 = string.lower(filter_letter)
--  variable2 = string.upper(filter_letter)
  list.clear()
  local a = tablelength(main_tab)
  for x = 1, a do
   ls = string.sub(main_tab[x],1,1)
   if ls == filter_letter then
--    if ls == variable1 or ls == variable2 then
     list.Items.Add(main_tab[x])
     list.visible = true
    end
  end
 end
end

function getFromList()
 --- get item from listbox and put to editbox
end

fm.show()
edt.onChange = lbCheck



EDIT 2 :
So, here is complete code. The last thing is to handle upper case / lower case on Editbox.

Code:
fm = createForm()
fm.width = 200
fm.height = 200
fm.caption = "TEST"

edt = createEdit(fm)
edt.left = 10
edt.top = 10
edt.width = 180

list = createListBox(fm)
list.top = edt.top + edt.height + 10
list.left = 10
list.width = 180
list.height = 100
list.visible = false

lbl = createLabel(fm)
lbl.left = 10
lbl.top = list.top + list.height + 10
lbl.caption = 'Double Click to Select'
lbl.visible = false


main_tab = {
"Albanian",
"Amazone",
"Baltimore",
"Bronx",
"California",
"Chile",
"Detroit"
}

function tablelength(T)
  local count = 0
  for _ in pairs(T) do count = count + 1 end
  return count
end


function lbCheck()
 local get_text = edt.Text
 if get_text == nil or get_text == "" then
  list.clear()
  list.visible = false
  lbl.visible = false
  else
  filter_letter = string.sub(get_text, 1, 1)
--  variable1 = string.lower(filter_letter)
--  variable2 = string.upper(filter_letter)
  list.clear()
  local a = tablelength(main_tab)
  for x = 1, a do
   ls = string.sub(main_tab[x],1,1)
   if ls == filter_letter then
--    if ls == variable1 or ls == variable2 then
     list.Items.Add(main_tab[x])
     list.visible = true
     lbl.visible = true
    end
  end
 end
end

function getFromList()
 a = list.ItemIndex
 z = list.Items[a]
 edt.Text = z
end

fm.show()
edt.onChange = lbCheck
list.onDblClick = getFromList
