Is there some attribute that can be used in the element that will cause the item’s sign to not be displayed? I realize that the showItemSign function can be called to do this after the XML is loaded, but I want to set this in the XML if possible. The item will be open, and I don’t want to show the (-) sign, and I don’t want to allow the user to be able to collapse the item.
There is no way to fully remove item sign from XML, but you can made disable it by
<item open=“1” closeable=“1” …
such item will be rendered as open one, and will not react on closing attempts
Full list of tree XML attributes can be checked at docs.dhtmlx.info
