MDL Multicolumn combobox

we have a dialog containing a combobox that has a multicolumn list model

Post your resource definition of the ComboBox.  For example...

DItem_ComboBoxRsc COMBOBOXID_LevelName =
{
  NOCMD, LCMD, NOSYNONYM, NOHELP, MHELPTOPIC,
  HOOK_CBO_LevelName, NOARG,
  36, "", "", "", "", NOMASK,
  0, 12, 4, 0, 0,
  COMBOATTR_READONLY | COMBOATTR_DISPLAYALLCOLUMNS | COMBOATTR_FONTBYCOLUMN | COMBOATTR_FULLWIDTH,
  TXT_LevelPrompt,
  "g_vars.prefs.levelName",
  {
    { 14*XC,  36, ALIGN_LEFT, TXT_LevelName }
  }

  }

This is the contents of the .r file:

DItem_ComboBoxRsc COMBOBOXID_TextFont =
{
  NOCMD, LCMD, NOSYNONYM, NOHELP, LHELP, NOHOOK, NOARG, 100,
  "", "", "", "", NOMASK, 0, 15, 5, 35*XC, 0, COMBOATTR_READONLY, "", "",
  {
    { 5*XC, 4, 0, ""},
    {25*XC, 25, 0, ""},
  }

};

COMBOATTR_READONLY

You could try some of the other COMBOATTR_ values (#defined in dlogbox.r.h), such as COMBOATTR_AUTOADDNEWSTRINGS.  I don't see a value for edit control.

You put me on the right track: the option to use is COMBOATTR_DISPLAYALLCOLUMNS
