plugin:Yalist's sample here executed:

1. Ordered list item 1
2. Ordered list item 2

3. Ordered list item 3…

   … in multiple paragraphs

4. Ordered list item 4

• Unordered list item

• Unordered list item…

  … in multiple paragraphs

1. Ordered list, first level
   1. Second level
      1. Third level
         1. Fourth level

   2. Back to second level

      1. Second?! What happened to third?

      Quiet, you.

2. Back to first level
3. Still at first level

Definition list

Definition lists vary only slightly from other types of lists in that list items consist of two parts: a term and a description. The term is given by the DT element and is restricted to inline content. The description is given with a DD element that contains block-level content. [Source: W3C]

Definition list w/ multiple paragraphs

The style sheet provided with this plugin will render these paragraphs…

… to the left of the term being defined.

Definition list w/ multiple “paragraphs”

Another way to separate blocks of text in a definition…

… is to simply have multiple definitions for a term (or group of terms).

This definition list has DD tags without any preceding DT tags.

Hey, it's legal XHTML.

Just like DT tags without following DD tags.

? But DT tags can't contain paragraphs. That would not be legal XHTML. .. If you try, the result will be rendered oddly.

Solution with plugin:yalist for the issue raised here

Bullet Point Level 1, first line

• (1) Bullet Point Level 1, first line

  (2) Bullet Point Level 1, second line

  • (3) Bullet Point Level 2

    indent: <span>'s, here <wrap indent>indent</wrap> can be inside dd.

  • (4) Bullet Point Level 2

  (5) Bullet Point Level 1, third line

• (6) Bullet Point Level 1, first line

Bullet Point Level 1, first line
  ** (1) Bullet Point Level 1, first line
  .. (2) Bullet Point Level 1, second line 
    ** (3) Bullet Point Level 2
    .. <wrap indent>indent</wrap>:  ''%%<span>%%'''s, here ''%%<wrap indent>indent</wrap>%%'' can be inside ''dd''.
    ** (4) Bullet Point Level 2
  .. (5) Bullet Point Level 1, third line
  ** (6) Bullet Point Level 1, first line

Nesting seems to work fine.

with standard-means: Organicing it nesting-looking would not easy work (5 is the issue) by using \\-linebreak-tags):

Bullet Point Level 1, first line

• (1) Bullet Point Level 1, first line
  (2) Bullet Point Level 1, second line
  • (3) Bullet Point Level 2
  • (4) Bullet Point Level 2
    (5) Bullet Point Level 1, third line
• (6) Bullet Point Level 1, first line

Bullet Point Level 1, first line
  * (1) Bullet Point Level 1, first line \\ (2) Bullet Point Level 1, second line 
    * (3) Bullet Point Level 2
    * (4) Bullet Point Level 2 \\ (5) Bullet Point Level 1, third line
  * (6) Bullet Point Level 1, first line

Visual work arounds with wrap outdent (intend):

• outer 1a
• outer 1b
  • inner 2a
  • inner 2b
    outer 1c
• outer 2c
• outer 2c
  outer 1c

  * outer 1a
  * outer 1b
    * inner 2a
    * inner 2b\\ <wrap outdent>outer 1c</wrap>
  * outer 2c
  * outer 2c\\ <wrap indent>outer 1c</wrap>

List in definition list:

A list

• 1. point

  • 1.1

  text to 1. point

• 2. point

say a code

test code

  ? Definition

  ? Next definition

came up here: Issues with Yalist with order list numbering and bullets.

1. ordered 1.
2. ordered 2.
   • in between
   • in between
3. ordered 3.

  - ordered 1.
  - ordered 2.
    * in between
    * in between
  - ordered 3.

breaks the flow

1. ordered 1.
2. ordered 2.

• in between
• in between

1. ordered 3.

  - ordered 1.
  - ordered 2.
  * in between
  * in between
  - ordered 3.

3. ordered 3.
