End Sub

Private Sub TextBox1_Change()
    
    Dim I As Long, tmp As String, arr() As String
    Dim J As Long, ArrCount As Long, K As Long
    
    With Me.ListBox1
        .Clear
        .Height = 0

    'Filling the Array with Values which matches the criteria
    With Sheet1
        J = .Cells(.Rows.Count, 1).End(xlUp).Row
        For I = 1 To J Step 1
            If InStr(1, .Cells(I, 1).Value, Me.TextBox1.Text) > 0 Then
                tmp = tmp & .Cells(I, 1).Value & "|"

        .Top = Me.TextBox1.Height + Me.TextBox1.Top
        If tmp <> vbNullString Then
            tmp = VBA.Left(tmp, Len(tmp) - 1)
            Erase arr
            arr = VBA.Split(tmp, "|")
            ArrCount = UBound(arr)
            For K = 0 To ArrCount Step 1
