Concept of list directive in Advanced PDF.

In Advanced PDF, the <#list> directive is used for iterating over a collection of items, such as a list or an array, in order to generate repetitive content within the PDF document.

Here’s a brief explanation of the concept and usage of the <#list> directive in Advanced PDF:

Syntax of the <#list> directive is given below:

<#list collection as item>
  <!-- Content to be repeated for each item -->
</#list>

1. Collection: The collection represents the data structure or variable that contains the items you want to iterate over. It could be an array, a list, or any other iterable object.
2. Item: The item is a temporary variable that represents each element of the collection as you iterate over it. You can use this variable within the block of code inside the <#list> directive to reference properties or perform operations on each item.
3. Content Generation: The content that needs to be repeated for each item in the collection is placed within the block of code between <#list> and </#list>. You can use the item variable to access properties or perform operations specific to each item.
4. Example:

<#list customers as customer>
  <p>Customer Name: ${customer.name}</p>
  <p>Customer Email: ${customer.email}</p>
</#list>

• In this example, customers is a collection (e.g., a list of customer objects), and for each customer in the list, the PDF will generate paragraphs displaying the customer’s name and email.
• The <#list> directive is a powerful tool for dynamically generating content based on collections in Advanced PDF templates. It allows you to create repetitive structures in your PDF documents, such as tables, lists, or any other repeating sections, based on the data you have available.
