Tracking with no Anchor

[block:callout] { "type": "info", "title": "Only for special integrations", "body": "If you are using anchor links for your recommended items (as most websites integrating LiftIgniter do) you can skip this section." } [/block] `$p("track")` searches through anchors on a specified element, and adds tracking tag & event listeners on the recommended items. If you aren't using an anchor to link your recommendations, then you'll have to trigger the custom `widget_shown`, `widget_visible`, and `widget_click` events yourself by using `$p("send")`. This is all handled by `$p("track")` if you are using an `anchor` tag on your widget, but this doesn't handle other cases since options are too broad.
