Checkboxes 2 Colums on Mobile

Hello,

i would like to have a form with pictures for checkboxes, this is no problem, but when i am in mobile mode, all my images all stack over another so i have only one vertical line. how can i make at least 2 checkboxes per line for mobile. so if i have 7 checkboxes it shows 2 per line an 1 at the bottom, hope i could explain my problem.

cheers
martin

Can you send a link to the page on your site where we can see the form?
