Σ_template example 2: block iteration

1. Simple block iteration

Basic parse() example. Filling a list from an array.

{list_item}

2. Nested block iteration

Let's fill a HTML table from a two-dimensional array.

{table_item}

3. Menu-like structures

This is used to output a sequence of elements that may have different presentation, consider things like normal and selected elements in menu. The much more complex example is the ITDynamic renderer of HTML_QuickForm.

{menu_title}
{menu_title} (you are here)

4. Methods to manually control removal of blocks

{item_title} edit
