Multiple components inside a 'oh-grid-col' on a Layout Page

The documentation says:
“Each column can host one widget from the standard standalone widget library, or a personal one.”

But I would like to host more then one widget in each oh-grid-col.
This would give me the option to have an view with 4 columns and dynamical filling status informations in each row. different status groups would be an card element and only visible of there is an error.

Any solution to this?
This is not working:

I think you should declare how many columns you’d like to have in every single row and then copy and paste the row themselves…

In this examples I’ve put 3 columns (each of them with a width of 33%) in a single row; You can easily set 4 or more columns (changing consequently their width) and then copy and paste the row as many time you want.
Just remember to increase the height of the f7-card-content (at the beginning) as well or you won’t see following rows.

Thanks for your helf and effort.
My problem is that I have in every column many informations which differ in height dynamically.
If for example in column number 3 a element gains much height the complete following row is pushed down.
Thats why I would like to use only 1 row with for example 3 columns. In these columns I would like to add many component cards below each other.

Is this possible in the meantime to have many widgets/card below each other in one column?

In the end, nearly all components just render to one or more html elements. When you are creating something complex with components, it helps to have some idea what it means for the underlying html. Most of the column options you have are just simple containers (an html element that exists only to hold and organize its child elements). The f7 containers default to either basic block display or flexbox for the placement and alignment of children, so if you want to know how to get multiple components in a column it’s best to understand a little of how flexbox works. There are hundreds of good flexbox explanations out there: this is one of my favorites:
