Is it possible to define a enumeration type expression? 2

[JerryWong]

So as the value of expression "A" can only be 1, 2, 3, when a part has several specs. I watched the video "Attributes and Expression Templates" by John. It uses a List Type attribute in Attribute Templates. But is it possible to do this more directly just in expressions dialogue box? Beginner to this. It will be great thankful if any advice to this.

First, let me preface my response by saying I'm not really sure of what the question is.

For this device the only available options for the adjustment are even numbers between 2 and 12.

These are the expressions used to take any input but return only even values between 2 and 12.

if(CUT_LEVEL<=2)(2)else(if(CUT_LEVEL>=12)(12) else((2+(round((CUT_LEVEL-2)/2))*2)))

For our example - if(CUT_LEVEL<=1)(1)else(if(CUT_LEVEL>=3)(3) else(round CUT_LEVEL))), where "cut_level" would be replaced by the expression name of your choice.

Make this way:
Create a expression like "D1" = 10
Crate a expression like "D1_options" = {10,20,30}

Now the D1 expression will have a list of options.

Yes, gelsonnicoletto you got what I mean. But I'm too stupid to understand how to do in detail. D1 and D1_options don't have any association?

Just append "_options" on a new expression name to work

So I tried Gelson's tip. It took a while to notice the arrow in the formula field that displays the selection list.

It does list the available options but you can still manually enter any value you want.
