Spliting a model into parts that with fit on the plate

So im trying to print a post-it template organizer. There are about 9 different pieces to the file but when I opened the file in the lulzbot edition of cura this is what I get. I obviously need to split it up but have no idea how to go about doing that and Google searches just give me regular cura results or other programs entirely.

Please help

Select each individual object, and use file-> export selected to save as a separate object.

Load each separately for printing after they’ve been separated.

Ok I’ve got the whole export thing but how do I go about selecting a single piece? No matter which part I click they all get the green outline

Cura edition is 4.13.17 if that makes a difference
