Keeping element on page [structured]

Hello, 

I'm working with structured FrameMaker and trying to keep my function definition on a single page. I.e move to the next page if it does not fit. 

I have a container element for this function as below. I guess I need to add some Paragraph formatting options. But it's not clear to me what exactly do I need.  

I would expect something like KeepTogether but can't find anything that looks like this. 

And I don't understand why I have the first and last paragraph options. 

I'm new to FrameMaker and will appreciate any help. 

Regards, 

Ilya.
