Hello,
There is no built-in mutiselect inline editor, but you can create a custom inline editor and return any HTML element:
https://docs.dhtmlx.com/gantt/desktop__inline_editing.html#typesofeditors
Here is an example of how it might be implemented:

If you want to add an entry in the list with users, you need to use the updateCollection command:

Here is the snippet that demonstrates how it works:

Hi?
I tested the sample that you sent and I am having an error in explorer.
Can you check it?

get_value -> selectedOptions

Hello,
Looks like, it happens because Internet Explorer doesn’t support the selectedOptions property:

So, you need to iterate all options manually and check if they are selected. Here is the snippet that should work in IE:
