How do I add new options to my combo List?

I have view:combo, where I’m getting options/data for this from backend. I need add new options to this combo list when user manually enters anything it should add to that list.

Hello,
There are several variants.

  1. You can customize a) a Combo or b) a Suggest List and add new elements to add options like in these snippets :

    b) Code Snippet
  2. There is also a variant to use Text view + Suggest List instead of combo, like this Code Snippet
