Hope I don't seem dense, but could I get a bit more clarification?

Right now I am iterating through like this: <!--#in "objectValues('Folder')" sort=sort_code-->

... and pulling out certain properties of each folder: <!--#var "_['some_property']"-->

How do I achieve the same goal while picking the folder at a specific sequence? For example, I want to display some properties of the folders at indexes 2, 5, and 7 without iterating through all of the folders.

Thanks in advance for your help.

<!--#with "_(list = objectValues['Folder'])"--> <!--#in "[list[2], list[5], list[7]]"--> <!--#var some_property--> <!--#/in--> <!--#/with--> -Michel

I am trying to find a way to grab a specific index from an #in. I would like to use this much like an array in which I could ask for the object at index [i]. Is there a way to grab specific indexes from an #in without iterating through the entire list of objects?

No need to use #in if you just want one item:

<!--#var "sequence[index]"-->

you can slice too:

<!--#in "sequence[5:]"--> ... <!--#/in-->

gives you the fifth to the last element. Note the quotes. This is an evaluation of an expression.
