dhxCombo with userdata for each option

In the documentation says that I can use userdata like this : userdata object sets some user data for the item “key:value” pairs).

But how do I get there?

Any sample?

How to use?

Unfortunately it is not available to set the userdata for the dhtmlxCombo options. Could you please, share with the link, where the userdata for the combo is mentioned.


This is the article related to the dhtmlxForm and its items.
In that case this is the userdata of the combo item of the dhtmlxForm.
It is not available to add a userdata to the individual options of the combo item.
