/**
 * Class syntax_plugin_combo_list
 * Implementation of a list
 *
 * Content list is a list implementation that permits to
 * create simple and complex list such as media list
 *
 * https://getbootstrap.com/docs/4.0/layout/media-object/#media-list - Bootstrap media list
 * https://getbootstrap.com/docs/5.0/utilities/flex/#media-object
 * https://github.com/material-components/material-components-web/tree/master/packages/mdc-list - mdc list
 *
 * It's implemented on the basis of:
 *   * bootstrap list-group
 *   * flex utility on the list-group-item
 *   * with the row/cell (grid) adjusted in order to add automatically a space between col (cell)
 *
 * Note:
 *   * The cell inside a row are centered vertically automatically
 *   * The illustrative image does not get any [[ui:image#link|link]]
