Is it possible to specifically define a collapsible endpoint

[Robko]

Hi all

Firstly let me mention that I have a severe learning disability and am not tech savvy, so please if you intend to respond to this question ensure that it (preferably) includes graphics to describe the process and contains no technical jargon; every online article regarding this question has no mention of what I am about to ask:

I am using Word 2013 and am wanting to apply the expand/collapse feature to several areas in my existing document, everyone will know that it is easy to apply; but what I find frustrating is that when I collapse the desired text (half a page) I find out that everything from that point onwards gets collapsed.
How do I tell Word to collapse only a specific portion of the document and up to what point? I’m sure the solution is easy to achieve, but as mentioned before this isn’t addressed online.
Thanks in advance.

This is what I found from the support guide of Microsoft Office:
1. Collapse or expand parts of a document
2. Place your cursor in the heading.
3. On the Home tab, click the arrow in the Paragraph group.
4. In the Paragraph dialog box, click the checkbox next to Collapsed by default.
5. Click OK.
