How to change the available elements in the list in Bitrix, in deals, depending on the element selected in the previous list?

Question

Bitrix24

Good afternoon!

There is such a problem: There are two lists in Bitrix24 (cloud version). It is necessary to make it so that when a certain element is selected in the first list, the available elements in the second list change.

For example, there is a list1, it has two elements: e1 and e2.

When you select element e1 in list 1, elements ee1, ee2, ee3 are displayed in list 2 When you select element e2 in list 1, elements ee21, ee22, ee23
are displayed in list 2

Thank you in advance for your answer!

Answer 1

As far as I remember. in Bitrix24 there is no possibility to create dependent lists. Only third-party applications to watch.
