I would like to search hex in dropdown list by description.

If dropdown holds so many many item IDs, it is really annoying to find what a certain item's hex ID is.
So I want to find it by searching description(i.e. Item name).

Example:

Dropdown list is like
0001:ABC
0005:DEF
000A:EFG


Is it possible to find the entry of "000A:EFG" by searching "EFG"?
Is there anyway to search dropdown list?

Type "ABC" and hit the cursor down key before you hit enter, it should jump to the correct record (if exists). That's the closest I think.

How can I match a substring in dropdown?
for example, if I type cowl, it can match:
Vampire's Cowl

Tested with a sample list.

Code:
-- Create the main form
if frmMain then frmMain.Destroy() frmMain=nil end
frmMain = createForm(true)
frmMain.Caption = "Search and Selection Tool"
frmMain.Width = 400
frmMain.Height = 300
frmMain.Position = 'poScreenCenter' -- Center the form on the screen

-- 1. Create the ComboBox (Dropdown List)
local cbList = createComboBox(frmMain)
cbList.Name = "cbList"
cbList.Left = 20
cbList.Top = 20
cbList.Width = 150
cbList.Style = "csDropDownList"

-- Add items to the ComboBox
cbList.Items.add("Spell Book") -- index: 0
cbList.Items.add("Spell Scroll")
cbList.Items.add("The Grail")
cbList.Items.add("Catapult")
cbList.Items.add("0001:ABC")
cbList.Items.add("0005:DEF")
cbList.Items.add("000A:EFG")
cbList.Items.add("Spell Scroll")
cbList.Items.add("0005:DEF")

cbList.ItemIndex = 0 -- Select the first item by default

-- 2. Create the Edit Box (Search Text)
local edtSearch = createEdit(frmMain)
edtSearch.Name = "edtSearch"
edtSearch.Left = 180
edtSearch.Top = 20
edtSearch.Width = 100
edtSearch.Text = ""

-- 3. Create the Button (Search Button)
local btnSearch = createButton(frmMain)
btnSearch.Name = "btnSearch"
btnSearch.Caption = "Search"
btnSearch.Left = 290
btnSearch.Top = 20
btnSearch.Width = 80

-- 4. Create the Memo Box (Results Display Area)
local mmoResult = createMemo(frmMain)
mmoResult.Name = "mmoResult"
mmoResult.Left = 20
mmoResult.Top = 60
mmoResult.Width = 350
mmoResult.Height = 200
mmoResult.WordWrap=false mmoResult.ScrollBars="ssAutoBoth"
mmoResult.ReadOnly = true -- Set to read-only

--------------------- Search function  -----------------------
-- your controls names?
ddlist = cbList -- or form UDF1, controls: UDF1.CEComboBox1
reslist = mmoResult -- or UDF1.CEMemo1

function searchList(text)
  local searchTerm = string.lower(text) -- Convert search term to lowercase
  local items = ddlist.Items

  --reslist.Lines.clear() -- Clear previous results

  if searchTerm == "" then
    reslist.Lines.add("Please enter a search term.")
    return
  end

  reslist.Lines.add("--- Search Results for: '" .. searchTerm .. "' ---")

  local found = false

  -- Loop through ComboBox items
  for i=0, items.Count - 1 do
    local itemText = items[i]
    local lowerItemText = string.lower(itemText) -- Convert item text to lowercase

    -- Use string.find for case-insensitive partial match
    if string.find(lowerItemText, searchTerm, 1, true) then -- The last 'true' disables pattern matching
      reslist.Lines.add("(Index: " .. i .. ") - Found:")
      --ddlist.ItemIndex = i -- The drop-down list scrolls to the index of the found result.
      reslist.Lines.add(itemText)
      found = true
    end
  end

  if not found then
    reslist.Lines.add("No matches found.")
  else
    reslist.Lines.add("------------------------------------")
    reslist.Lines.add("Search complete.")
  end
end

------------------------ Search  Gui options  ----------------

-- Assign the click event to the Search button
btnSearch.OnClick = function()
  local text = edtSearch.Text
  searchList(text)
end

-- Cleanup when the form is closed
function formClosed(sender)
if frmMain then frmMain.Destroy() frmMain=nil end
end
frmMain.OnClose = formClosed

-- Show the form
frmMain.Show()

Thank you for your reply.
I implemented your script to my table, the search result only appear in a text, it's different from what I needed.

Sorry, I might have not explained my question thoroughly.

When I try to change a value of address with dropdown, a "change value" dialog popup.
When typing something in the text box, and press up or down on keyboard, it only matches the start of a string.
I want to make the input text becomes a filter for the dropdown list, and match any substring, not just the start, so I can click to select a value from the filtered list.

Thanks again.
After some research, I made a form with list box based on your code.
Unfortunately CE does not seem to support an event like OnDoubleClickValue for MemoryRecord class in lua.

you need to use
Code:

AddressList.OnValueChange=function(addresslist,memrec)
  if memrec.DropDownList.Count>0 then
    --show my own editor

    return true
  else
    return false
  end
end

Version 2.
Select from list, change (Apply button)
Filter, select, and change the list.
Filter terms apply only to values.
Search for value, select value, change value.

Code:

local ddlist = nil
local listTbl = {}
local mmoInfo
local selectedInfo = "true"
local key1 = ""

function load_ListOn()
    local addressList = getAddressList()
    local count = addressList.Count
    listTbl = {}

    if mmoInfo then mmoInfo.Lines.clear() end

    if count == 0 then
        if mmoInfo then mmoInfo.Lines.add("ERROR: Address List is empty. Cannot load data.") end
        ddlist.Items.clear()
        return
    end

    local loadCount = 0
    local addedValues = {}

    ddlist.Items.clear()

    for i=0, count - 1 do
        local record = addressList[i]

        local description = record.Description or ""
        local value = record.Value or ""
        local address = record.Address or ""

        if value ~= "" and description ~= "" then

            local itemData = { value = value, description = description, address = address, recordIndex = i }
            table.insert(listTbl, itemData)

            if value ~= "" then
                ddlist.Items.add(string.format("[%s] %s", i, value))
                addedValues[value] = true
                loadCount = loadCount + 1
            end
        end
    end

    if mmoInfo then mmoInfo.Lines.add(string.format("Data loaded: %d unique item values.", loadCount)) end
end

Thanks to both of you.
With the OnValueChange event I can finally replace the dropdown with filtered list box.
