MultiSelect possible even if multiSelect: false

[SplendidMinds]

Hey Community,

I have a TreeView which is using lazyLoad to navigate through the layers. Even so I have set multiSelect to false, multiSelection is still possible. Can anybody explain to me what am I doing wrong? Thank you.

var initSelectableTree = function() { return $('#treeview-selectable').treeview({ levels: 1, data: json, multiSelect: false, lazyLoad: function (node, dataHandler) { console.log(node); $.ajax({ url: "copy_tree_lazy.php?level=" + (node.level+1) + "&parentid=" + (node.id), type: "POST", dataType: "json", async: true, success: function(data){ dataHandler(data); } }); }, color: "#111152", showTags: true, showImage: true, highlightSelected: true, selectedColor: "#111152", selectedBackColor: "#F7E297", onhoverColor: '#E2E2F9', onNodeSelected: function (event, node) { selectItem(node.level,node.id); } }); };
