Update options of a richselect dynamically in activecontent

I have a richselect activecontent in which i want to load data dynamically. Initially the richselect has no options. Is it possible to load options later in the richselect activecontent or to give unique id to the activecontent elements ?

Hello,

The ActiveContent mixin is useful for the simplest controls and is not designed for something more complex. From now on, we stronger than ever recommend stable solutions for simple things – HTML templates for simple icons, buttons, and the like, while for complex views you can use DataLayout.
