    How to efficiently remove subitems? Posts

    Hi,

    I need to remove sub-items from a tree item and I was wondering how to do that efficiently? Currently I have a loop which goes over all sub-items and calls removeItem. This is painfully slow mainly because _render is called for every item. This also happens when the parent item is collapsed so subitems are not even visible. I must be missing something obvious? Why there’s no beginUpdate/endUpdate pair list there is for treeGrid?

    Please help 🙂

    Hello sqward,

    Unfortunately, a loop is the only way to remove multiple tree items. The methods beginUpdate and endUpdate are not part of jqxTree’s API.
