* Parameters:
* @param completed - if ="completed" then green presentation with checkbox

* @param id - that is the correspondent id in the mirror tool (like Agenda item 2)
* @param type - that is the correspondent type in the mirror tool (like this is a Link item)
* @param builder - if ="builder" then onclick shows in new window
* @param icon - if ="icon" then the small icon will appear
* if ="wrap" then wrapped settings are used (and no icon is displayed)
* if ="nolink" then only the name is returned with no href and no icon (note:only in this case, the result is not displayed, but returned)
