Hi Simonwp
Of course it’s possible. Drag however many instances of the widget you are using to the shortcode sidebar, either use multiple [do_widget ..] s or [do_widget_area …] as per https://www.ads-software.com/plugins/amr-shortcode-any-widget/#installation
As for how it looks in your page & theme – If it doesn’t look right, You need to work out how to do this yourself using css for your theme and widget. See the ‘styling section’ here: https://www.ads-software.com/plugins/amr-shortcode-any-widget/#faq
It depends on the width of your content in your theme with the various devices that you anticipate you viewers using, and the width of the content of whatever widgets you trying to display.
Use css to set the widths
Use css to either float the items up next to each other, or other css method as suits your theme and requirements.
