See attached GIF. Does anyone know what is going on here? The “true” branch (_List.DropItems_) is being executed no matter what the input is. This is driving me crazy!

It looks like false is _almost_ executing as intended; the problem is that the output seems to cut to the smaller list size (4 elements) between the two options.

EDIT: [here’s an old conversation on the topic, contains a solution](https://forum.dynamobim.com/t/if-statement-output/8134/2)

In this case and with the _If_ node, the length of the result is always truncated to the count of the _shorter_ option
