Description

List groups are a flexible and powerful component for displaying not only simple lists of elements, but complex ones with custom content.


Two onclick events happen when a Dropdown is clicked. When the control is initially clicked, an event is sent. When the user makes a selection, onclick is called again with the text of the selection.

Popovers and Tooltips are supported.

Properties and Methods

Standard properties are supported, plus:

appearances Appearance of each item, one per line. Can be default, success, info, warning or danger. Design time.
addItem(item, type, appearance) Adds an item to the end. item can be HTML - characters like LF and CR should not be included.

type can be "active" or "disabled". Runtime.

clear Clears all items. Runtime.
itemBadges Badges to show, one per line.
items Items to show, one per line. Prefix * for disabled, > for selected, ! for heading (not all controls support headings). Design Time.
length Current number of items. Runtime.

Events

Standard events are supported. For this control, the onclick event will be most useful.

Example (Basic)

Function Listgroup1_onclick(choice)
  MsgBox "The choice is " & choice
End Function

Set and unset the 3rd line to active:

$("#Listgroup1_2").addClass("active")
$("#Listgroup2_2").removeClass("active")

Change the text of line n:

$.NSB("Listgroup1_" & n).textContent = "New text"

Change line n as html:

$.NSB("Listgroup1_" & n).innerHTML = "New text"

Change line 1 as html and set the badge:

Listgroup1_1.innerHTML = "<i>item 2</i><span id='Listgroup1_1_badge' class="badge">2</span>"

Example (JavaScript)

Ignore the event when the Dropdown is first clicked, and handle the event when a selection is made.

Listgroup1.onclick = function(choice) {
    NSB.MsgBox("The choice is " + choice);
};

Set and unset the 3rd line to active:

$("#Listgroup1_2").addClass("active");
$("#Listgroup2_2").removeClass("active");

Change the text of line n:

$.NSB("Listgroup1_" + n).textContent = "New text"

Change line n as html:

$.NSB("Listgroup1_" + n).innerHTML = "New text"

Change line 1 as html and set the badge:

Listgroup1_1.innerHTML = "<i>item 2</i><span id='Listgroup1_1_badge' class="badge">2</span>"
