    I have a requirement where I need to enable check boxes as well as allow drag and drop. But when you do this the toggle is not working. Once you remove all the children from a node and then add a child the toggle icon does not appear. Please find the modified sample code:

            can populate it from 'UL' or by using its 'source' property." />

    Hello benin10,

    The two jqxTree widgets are not consistent.
    I would suggest you as a workaround you could clear all content (all items – clear method) and after that could re-create the whole Tree.
    You can get all items by getItems method of the jqxTree and return them back by some of the add methods – addTo, addBefore and addAfter.

    Best Regards,
