I decided to test the MIGX functions but discovered that the version of Modx for which I found the manual is evidently much older than my 2.2.14. So I cannot guess what are new names for the fields like 'Form Tabs', 'Grid Columns' and '"Add Items" Replacement'. Could you give me a hint? I'd prefer a screenshot because I use a Russian version of Modx and the names of the fields may differ from word-to-word translation.
nothing has changed regarding the naming of this fields.
You can change the manager-language temporarly to find the fields.
