Conditional statements or scripting in "Book list template" ?

Boilerplate4U · 08-30-2021, 12:27 PM

Is it possible (and if so how) to use conditional statements or scripting in "Book list template"?

I've got a custom column called "#winner" of type yes/no that I'd like to present only if it's set to yes..

No, it's a very simple template language. No scripting, conditional expressions. IIRC yes/no columns become yes or no only.

Ok, thanks for the prompt reply! Cheers!

I haven't tried this but I suspect you could make a "Column built from other columns" (composite columns) that computes the result you want, then use that column in the book list template.

Composite columns use the full template language, which supports conditionals and computation.

While not quite the same thing, device save paths are limited to the simpler template too, so I created a composite column called #kobopath and used that in the path.
