Problem description:
I recently encountered a problem using jstree. When the parent node is selected, the disabled child nodes will also be selected as follows

2. Modify the checkbox plug-in configuration and set cascade_to_disabled to false (note: the configuration script needs to be placed after jstree.min.js)
<script src="./../../dist/jstree.min.js"></script> <script> $.jstree.defaults.checkbox = { visible: true, three_state: true, whole_node: true, keep_selected_style: true, cascade: '', tie_selection: true, /** * This setting controls if cascading down affects disabled checkboxes * @name $.jstree.defaults.checkbox.cascade_to_disabled * @plugin checkbox */ cascade_to_disabled : false, cascade_to_hidden : true }; $('#data').jstree({ 'core' : { 'data' : [ { "text" : "Root node", "children" : [ { "text" : "Child node 1", "state": { "disabled": true } }, { "text" : "Child node 2" }, { "text" : "Child node 3" }, { "text" : "Child node 4" }, { "text" : "Child node 5" }, { "text" : "Child node 6" } ]} ] } ,"plugins" : [ "checkbox" ] }); </script>
