GitLab: How to add (remove) extra line space on markdown bullets/lists?

Question

I've found related question, mine about GitLab, those about GitHub: How to remove extra line space on GitHub markdown bullets/lists? and one answer is to use 4 spaces and another:

You cannot do this ... This is due to GitHub's styling of the markdown, not an inherent issue with the markdown itself.

I've made a list and in GitLab GUI I see it like that:

o ABC

o ABC

  o ABC
  o ABC
o ABC

Extra empty line before secondary list but no line after. I prefer to add space after secondary too, however deleting all empty lines in list would look good too. Below is my markdown, it has 4 spaces for secondary list and I've tried to add <br/> as per Create two blank lines in Markdown but it breaks list structure after that (which also results in disappearing empty lines between primary list entries btw).

  - datapool
  - specific
    - jmx
    - config
<br/> (that is temp try, see above text)
  - python

Could it be done in GitLab?

Answer 1

I found that alternating between the + and - unordered list indicators produces the desired result.

- Item 1
   - SubItem 1
   - SubItem 2

+ Item 2
  + SubItem 1
  + SubItem 2

- Item 3
   - SubItem 1
   - SubItem 2

Answer 2

Small mistake: should have put <br/> on same level as secondary list (indent with 4 spaces) - then extra line is seen in GUI.
