How to add a menu item in one of the list items ?

Hi ,

I have a list with items having the names of tabs.
Clicking on each item I am opening a tab in a tabview.
I need one of the list items to show a menu (or submenu may be) when clicked, for example the B-Tab in this snippet https://snippet.webix.com/oimc4mzn

If I click on B-Tab in list, it will show the content which is implemented in the snippet now. But if the menu is clicked then it will show a different content there itself.

How to insert a menu in the list item instead of a plain text ?

Thanks

you can use menu view with layout:“y”
