Hi,
Unfortunately there is not option for that, it was designed to be displayed in a column, one after another.
You could however try a custom CSS code to force a wrapping flex layout:
[html]form[name=options] fieldset {
width: 100% !important;
}
.asp_sett_scroll,
.mCSBap_container {
display: flex !important;
flex-wrap: wrap;
}
.asp_option {
display: flex !important;
}[/html]
Please that this falls into a customization request category, so I can’t guarantee that this code will work in all cases, under all circumstances.
