Dear Dev,
as an app Mendix Developer, I edit on lot off apps. when need to edit multiple columns and rows you have to edit them one by one, I think you would agree with me this is no efficient and time consuming. please an option to multi-select and Edit them all at once, this kind of feature are available in Most of the Applications. where you can click on an item, press control/command and select multiple items with mouse. this would be more productive and less time consuming.
thankyou..
The multi-select feature is available with the new release 9.20 and extended in 9.21. Please have a look here: https://www.mendix.com/blog/mendix-release-9-21-enjoy-the-presents/
Surely, these new enhancements make development a lot faster. Was that more or less what you had in mind?
