Hi, I have tradition master-detail pages layout in whole app, but on this page I need to invert sizes (did it by adding custom divs flexbox css --see gif).
But I’d like to make it responsive, cause all need to be included in a tag, if using simple
Anyone can help pls? 
There is no such thing as inverted master detail. If you need to do something responsive:
- you can use side panels (which can be nested into the page) with breakpoints
- just use CSS media queries to hide/show something based on screen size
ok will try thanks
