+## Gestione ID dei form element
+Gli ID dei campi del form (es. nel Dropdown, Checkbox, TextField) che vengono creati con i vari metodi `create...` in `ElixFormsComponentAbstract.tsx` non devono mai essere cambiati o manipolati (es. aggiungendo suffissi come `_dropdown`), poiché vengono ricevuti e inviati da una pagina iniziale che si basa strettamente sul loro nome e ID esatto. In caso di conflitti di ID (es. dovuti a input nascosti), il suffisso va applicato agli altri elementi (come l'input hidden) e MAI all'elemento principale visibile.
