I suppose it might be helpful to build it in such a way that we could maintain a separate array of valid widths (like in a constant) then have a rule simply iterate over that list and find the valid width (if any).

/* rule!GLBL_getPageWidth() */
a!localVariables(
  local!widths: {
    "PHONE", "TABLET_PORTRAIT", "TABLET_LANDSCAPE", "DESKTOP_NARROW", "DESKTOP", "DESKTOP_WIDE"
  },

  index(
    a!flatten(a!forEach(
      local!widths,
      if(
        a!isPageWidth(fv!item),
        fv!item,
        {}
      )
    )),
    1,
    "Unknown"
  )
)

It does seem a bit backwards that we require such a work-around to GET the current page width - to me it seems like there should've just been a "a!pageWidth()" function that RETURNS the current page width, i.e. the inverse of what we have to do with a!isPageWidth. I assume they have reasons, but...

Hi it is not having exact same as you want but please check the stackWhen component on the columns layout https://docs.appian.com/suite/help/22.3/Columns_Layout.html

Edit: You can try this

a!richTextDisplayField(
  value: 
  if(
    a!isPageWidth("PHONE"),
    "PHONE",
    a!isPageWidth("DESKTOP"),
    "DESKTOP",
    a!isPageWidth("DESKTOP_WIDE"),
    "DESKTOP_WIDE",
    a!isPageWidth("DESKTOP_NARROW"),
    "DESKTOP_NARROW",
    "i DONT KNOW"
  )
)

a!isNativePhone() and a!isNativeTablet() both functions are deprecated from appian new version.
And these functions will return true/false.
But my requirement is dt it has to return screen type only.
