Collapse/expand all no slide effect

[Mark]

Hi,

 I've added a collapse/expand all option to my treeview, which works fine, but doesn't have any slide effects.  On the demo one (http://demos.telerik.com/kendo-ui/treeview/api) it has slide effects for this.

Are there settings I need to apply somewhere to make this work?  I have 3 treeviews on top of each other and my button works for all at once - here are the relevant bits of javascript code :-

// 1. collapse all treeview nodes
var treeview = $("#TreeViewSurveyByRisk").data("kendoTreeView").collapse(".k-item");
var treeview = $("#TreeViewSurveyByRecAction").data("kendoTreeView").collapse(".k-item");
var treeview = $("#TreeViewSurveyByLocation").data("kendoTreeView").collapse(".k-item");

// 2. expand all treeview nodes
var treeview = $("#TreeViewSurveyByRisk").data("kendoTreeView").expand(".k-item");
var treeview = $("#TreeViewSurveyByRecAction").data("kendoTreeView").expand(".k-item");
var treeview = $("#TreeViewSurveyByLocation").data("kendoTreeView").expand(".k-item");

Any help would be appreciated.

Thanks, Mark

Hello Mark,

The described behavior can be observed if the widget is bound to remote data - this is a known limitation. On initial expand there will be no animation, however on every consecutive expand / collapse the animation should be present. If your case is different from the one mentioned above we will need an isolated runnable example in order to test the issue locally and provide concrete recommendations.

Thanks Plamen,

It's not a major issue so I'll have a play around with what's there.

Thanks,
