Unless you delete the fold, it should remain even after you expand it.
You can see a visualization of your folds by setting some appropriate
value (roughly how many fold-levels you expect to nest) to
'foldcolumn' such as

:set foldcolumn=4

You can use

za

to toggle folds under the cursor, or

zR

to expand all folds in the entire file and

zM

to collapse all folds in the file. There's also

zX

to reset all open/closed folds so that they return to 'foldlevel'

And of course, there's

zo
zO

to expand ("open" is my mnemonic) one/all folds under the cursor and

zc
zC

to close all folds under the cursor. If you start reading around

:help zo

there are a lot of commands for opening/closing and jumping between
folds that should get you what you need.

Usually

zC

should do this for the section containing the cursor, or

zM

for all folds everywhere.
