Help with ‘list’ component wuthin UI builder pls.
I’m working may way through Cookbook, ‘How to create a dropdown in UI Builder’

But the ‘list’ component is no longer shown and I’m unfamiliar with their replacements.
from cookbook blog -

new list components -


You could use next logic:

Comparator is no needed in Remove block, because it’s used for nested field of an item.

For example you want to iterate over array of objects like:

[{foo: 1, bar: 3}, {foo: 2, bar: 2}] and compare field ‘foo’ in this objects, for this purpose comparator should be ‘foo’
