Hi,

Try using mdb.Treeview isntead of Treeview. You can also try importing Treeview with <script type="text/javascript" src="plugins/js/treeview.min.js"></script>. Here is the instruction for plugins installation https://mdbootstrap.com/docs/standard/pro/plugins-installation/. And I will provide snippet showing how to use getInstance, as well: https://mdbootstrap.com/snippets/standard/d-wajszczuk/3290665#js-tab-view.

Keep coding,
Dawid

I tried both solutions but no luck. Have a look at attached screenshot . When i log in console Treeview it returns a Module {__esModule ...} not an instance with method. So does this have to do with transpiling issue ? error treeview

There is something wrong with your import of Treeview, because it is Module instead of function. Try adding type="text/javascript" to your script tags with plugins' JS code. If you are importing our code with import statements, try using require statements instead.

Try using our starter (zip package that you have downloaded with MDB-UI-KIT - without any modifications). Open index.html, copy one example from our documentation https://mdbootstrap.com/docs/standard/plugins/tree-view/, try to get instance of this Treeview and let me know if this works. It is hard to tell what is going wrong from this screenshots.
