Virtual Scroll Options

[ghost]

Hello, I have issues with slow ui when I have several nodes (1-2k) is there any way to implement virtual scroll? Below is a short, incomplete snippet of my use:

<ul frang-tree cmc-context-menu menu-data="contextMenuData" on-show="onContextMenuShow" pass-through="getContextMenuPassThroughData()" id="{{callee}}-tree-top-node" style="margin:0px;" > <li frang-tree-repeat="node in treeData track by $index" frang-tree-drag="{node: node, parent: $parent.node}" frang-tree-drop="processNodeDropFunction(node, dragData.node, dragData.parent)" frang-tree-allow-drop="shouldAllowNodeDropFunction(node,dragData.node,dragData.parent)" ng-class="{'selected':node.selected, 'highlighted': searchString && node.label.toLowerCase().indexOf(searchString) > -1}" object-identifier="{{determineObjectIdentifier(node)}}" >
