A section may have as many multilevel lists as you need. Creating a list with PDFFlow is only a few lines of code:</p> <ol> <li>First you need to create DocumentBuilder.</li> <li>Then add Section to it.</li> <li>Now add as many Paragraphs to Section, as many list items you need.</li> <li>Make each Paragraph a list item, set level and style if needed.</li> </ol> <p>You can make a paragraph an item of a <strong><em>numbered</em></strong> multilevel list using the <em>ParagraphBuilder.SetListNumbered</em> method. For each item, you can specify the numbering style, the level of the list, the left indent, and enable the hierarchic numeration is necessary. Items of a numbered list are numbered automatically on each level. The available numbering styles are: Arabic numbers, lower and upper Roman numbers, lower and upper Latin letters, lower and upper Cyrillic letters.</p> <p>You can make a paragraph an item of a <strong><em>bulleted</em></strong> multilevel list using the <em>ParagraphBuilder.SetListBulleted</em> method. For each item, you can specify the bullet symbol, the level of the list, and the left indent. The available bullet symbols are a <em>bullet</em> and a <em>dash</em>.</p> <p>The default level left indent for a multilevel list is 20f, the default numbering style of a numbered list is Arabic, the default bullet symbol is Bullet. You can configure the formatting settings of list items directly or apply a style to them using methods of ParagraphBuilder. You can also set a style for all lists in the section using the <em>SectionBuilder.SetListStyle</em> method. In this case, you can use the <em>ParagraphBuilder.SetList</em> method to quickly make the necessary paragraphs list items and the set style will be applied to all list items in the section automatically.</p> <p>Once a paragraph which is not an item of a multilevel list is met, the multilevel list is considered completed. When later another paragraph is made an item of a multilevel list, it becomes the first item of a new multilevel list, and its automatic numeration will start from the beginning.</p> <p><strong>Examples</strong></p> <p>​</p> <p><strong>Example 1.
