Columns in Accordion-Item

[STFNJNG]

I'm trying to get a grid layout in an accordion item. My markup is like:

=> class accordion
=> class accordion-item => class accordion-content
When I'm trying to put a inside of content and then some div's with different sizes (i.e. small-3, small-3, small-3, small-3) all these div's are in a new row instead side by side ..

DIV

DIV

DIV

DIV

instead of

DIV DIV DIV DIV

Has someone an idea or a small example-code? or generally: is it possible to do the grid inside of an accordion?

Kind regards and thanks in advance.
