Add new items to already created form

Hello,

Is there any way to add items to an already created form? in dhtmlx 5 we used addItem but in dhtmlx8, we are not able to.

thank you.

There is no possibility to modify the structure of the form dynamically.
I can suggest you to use the predefined hidden controls, showing them on a needed condition.
Otherwise I can only suggest you to rebuild your form with a new needed configuration of controls.
