LO Writer "Custom Ordered List Levels" in a document template

[wawawriter]

Howdy,

What I want to do: Save a .ott where the default ordered list has specific levels. I have customized the Bullets and Numbering" levels to look like:

• Level 1: 1.
• Level 2: a.
• Level 3: ●

What I have tried:

• I have found several threads including https://ask.libreoffice.org/t/paragraph-styles-multilevel-lists/68708 that describes how to save certain aspects of a List Style to a Paragraph Style for a template
• I have not found a solution that allows me to quickly apply the three custom “levels”

From here: Does anyone have any tips or articles that I could research that might help me learn how to save my custom list levels?

As already mentioned in the referenced question and my answer, you must define a custom list style. The reason is Format>Bullets & Numbering customisation does not persist across session. This is a design decision because Bullets & Numbering is a dirty compatibility feature intended no to upset Word users. It tries to implement a one-size-fits-all feature with all the compromises implied by this generality.

Your first task is to learn how to create a list style.

Then you must decide how you’d use this styles. There are two schools for it.

• a manual method akin to manual formatting where you explicitly apply the style when you need it,
• a more formal approach where you attach the list style to a paragraph style
  When you apply this paragraph style, the numbering automatically appears. This second method is more rigorous but you have to design your document in a semantic approach, i.e. every style is associated with a significance, not a visual effect, like heading, note, comment, important, main topic, citation, …

A template .ott is mainy intended to store styles. Therefore this is the perfect place for your (persistent) custom list style.
