Totem makes vertical tickers easy to implement by:

• Turning a list of items into an animated ticker that auto-advances
• Specifying anchors for stop, start, next, and previous navigation links.

Installation

Load jquery.totemticker.js or the minified jquery.totemticker.min.js script. Call the totemticker function on a UL or OL element. An example is below.

$('#vertical-ticker').totemticker({
row_height  :   '100px',
next        :   '#ticker-next',
previous    :   '#ticker-previous',
stop        :   '#stop',
start       :   '#start',
});

Options

The following options are available via the plugin array. Defaults are listed below.

next        :   null
previous    :   null
stop        :   null
start       :   null
row_height  :   '100px'
speed       :   800
interval    :   4000
