How to create a list without indentation? | iText 5 PDF Development Guide

Is it possible to create numbered lists without any indentation?

Something like:

Please take a look at the ListNumbers examples.

When we create an ordered list like this:

We get a result like this:

List with indentation

Where necessary, extra space is added between the label and the content of a list item.

Your question is: how can we remove this indentation. That's a matter of adding a single line to your code:

Now the result looks like this:

List without indentation

As you can see, no extra space was added after items 8 and 9.

This answer is so simple that I can't believe that this was actually the whole question (if it was, that would mean that you didn't do any effort whatsoever yourself). Looking at the desired result, I assume that there is more at play then what you mention in the subject of your post.

I see:

• Custom numbering: no . after the number.

• A nested structure: 2, followed by 2_1, and so on.

Changing the list symbol in case of ordered lists can be done using the setPreSymbol() and setPostSymbol() methods.

Take a look at this snippet:

First we remove the dot that is added after each number automatically, we use the getPostSymbol() method for this:

Then we nest list inside list3. As we want to get a result that looks like 8_1, 8_2, 9_1, etc., we use the setPreSymbol() method like this:

Now the result looks like this:

Using pre- and post-symbol

Obviously, one could argue: why do you want to use a List for this kind of result? Why not just a series of Paragraph objects. However: if you're creating Tagged PDF, it's better to use List because iText will then automatically tag that content as a list (e.g. in the context of accessibility).
