How to markdown nested list items in Bitbucket?

Possibilities

• It is possible to nest a bulleted-unnumbered list into a higher numbered list.
• But in the bulleted-unnumbered list the automatically numbered list will not start: Its is not supported.
• To start a new numbered list after a bulleted-unnumbered one, put a piece of text between them, or a subtitle: A new numbered list cannot start just behind the bulleted: The interpreter will not start the numbering.

In practice

1. Dog
2. German Shepherd - with only a single space ahead. 2. Belgian Shepherd - max 4 spaces ahead.

• Number in front of a line interpreted as a "numbering bullet", so making the indentation. * ..and ignores the written digit: Places/generates its own, in compliance with the structure. * So it is OK to use only just "1" ones, to get your numbered list. * Or whatever integer number, even of more digits: The list numbering will continue by increment ++1. * However, the first item in the numbered list will be kept, so the first leading will usually be the number "1".
  1. Malinois - 5 spaces makes 3rd level already.
     1. MalinoisB - 5 spaces makes 3rd level already.
     2. Groenendael - 8 spaces makes 3rd level yet too.
     3. Tervuren - 9 spaces for 4th level - Intentionaly started by "55".
     4. TervurenB - numbered by "88", in the source code.

87. Cat
88. Siberian; a. SiberianA - problem reproduced: Letters (i.e. "a" here) not recognized by the interpreter as "numbering".

• No matter, that it is indented to its separated line in its source code: The indentation is ignored here. 2. Siamese
• a. so written manually as a workaround misusing bullets, unnumbered list.

4 spaces do the trick even inside definition list:

Endpoint
: `/listAgencies`

Method
: `GET`

Arguments
:   * `level` - bla-bla.
    * `withDisabled` - should we include disabled `AGENT`s.
    * `userId` - bla-bla.

I am documenting API using BitBucket Wiki and Markdown proprietary extension for definition list is most pleasing (MD's table syntax is awful, imaging multiline and embedding requirements...).

This worked for me in Bitbucket Cloud.

Entering this:

* item a
* item b
** item b1
** item b2
* item3

I've got this:

Use 4 spaces.

# Unordered list

* Item 1
* Item 2
* Item 3
    * Item 3a
    * Item 3b
    * Item 3c

# Ordered list

1. Step 1
2. Step 2
3. Step 3
    1. Step 3.1
    2. Step 3.2
    3. Step 3.3

# List in list

1. Step 1
2. Step 2
3. Step 3
    * Item 3a
    * Item 3b
    * Item 3c

Thanks @Waylan, your comment was exactly right.
