Combo Box component in svyNavigation navbar

I am quite new to Servoy development and am currently wanting to add a Combo Box to the nav bar using the svyNavigation module; I have not found anything relating to the types of components themselves in the wiki (https://github.com/Servoy/svyNavigation … Navigation) and it would be great if I could get any pointers to how to add a Combo Box to the nav bar in the overridden loadNavbarItems() function.

I am assuming that the data list in the combo box would be added by using the navigationItem.setCustomData(customData) function but, again, I am not sure and it would be great to know how to set a component up.

Thanks,

svyNavigation looks like it has lots of potential. Is it possible to place mini-forms with elements like combos, or stacked fields?
