autoHide Boolean(default: true)

Specifies if the Tooltip will be hidden when the mouse leaves the target element. If set to false, a Close button will be shown within Tooltip. If set to false, showAfter is specified, and showOn is set to mouseenter, the Tooltip will be displayed after the given timeout even if the element is no longer hovered.

Example - preventing the Tooltip from closing automatically

<span id="target" title="Tooltip content">
    Some Content
</span>

<script>
    $(document).ready(function() {
      $("#target").kendoTooltip({
        autoHide: false
      });
    });
</script>
