(Outlook Search bar, a combination of a menu item where the selected menu item text is shown combined with a search textbox and optionally the tiny dropdown icon to support a custom dropdown form with more search fields.
the first menu item should be caption of the button
when a menu item is selected the caption of the button should be set to the selected item
the input caret is on top of the search icon in the textbox.
Ideally this should be embedded in once control and the set/get value should return an object with the input text and selected button and/or the the values from the dropdown form.
