Incorrect tabIndex in dhx.menu

How can you make the tabIndex go in order for each menu option by adding its submenu before the next main menu option?

I have tried with the parent property but it builds the submenu in another div and the tabindex doesn’t include the children in its ordering.

The JSON file is correct but the submenus are built independent of their parents, it doesn’t save the ul/li hierarchy…

Could you please, provide a complete demo or a snippet, where the problem can be reconstructed locally?

For example:

The tab order is: Tab1 (enter) Tab2 Chil1 Child2…
But we want: Tab1 (enter) Child1 Child2 Tab2…

Is posible?

Unfortunately it is not available to modify the tab-index for a dhx.Menu.
