We are on Appian 7.7 , while adding instructions to SAIL components like a!dropd

Have you tried char(10) and/or char(13)?

I tried using the below text but the live view shows it all in one line,

instructions: "a.          Use option one to do abc " & char(10) & char(13) & "b.          Use option two to do xyz",

instructions: "a.          Use option one to do abc " & char(30) & "b.          Use option two to do xyz",

Any other suggestion Abhi?

I have tried this in the past and it did not work for me either. It seems that char(10) or char(13) do not work in the instructions property. However, when these functions are combined with Rich text display functions, they work as expected. Eventually, I displayed entire instruction text in a single line and that was acceptable to some extent.

Hi Manoj,
Place a paragraph field below the dropdown field make sure the label is empty and the label position is similar to that of the dropdown field, then using the below code its doable. Here the instructions are passed as rule inputs. PFA screenshot for reference.
a!paragraphField(
label: "",
labelPosition: "ADJACENT",
value: ri!firstInstruction & CHAR(
13
) & ri!secondInstruction,
saveInto: {},
readOnly: true(),
refreshAfter: "UNFOCUS",
validations: {}
)

Hope it helps!

Thanks Sonal, I tried with richTextField first but your solution looks better.
