A List object lets you to display all the elements in a list, or a preset number of elements (Step attribute defined with value > 0). The columns in the list are defined by the objects (Adelia tags) present between the list opening tag, <adelia:b_list/> 
, and the list closing tag, <adelia:e_list/> 
.
When a list is defined with a step, it may be necessary to manage an ::ADELIA_ROLLUP (or possibly ::ADELIA_ROLLDOWN) event to manage list rolling.
The presence of an <adelia:b_list/> tag determines a link with the Adelia Web program to which the current HTML page belongs. The <adelia:b_list/>tag creates a list in the program's data environment, for which the field definition is given by the objects enclosed within the <adelia:b_list/> and <adelia:e_list/> tag.
