Column option doesn't break list into columns

I will be taking a closer look at this. Thank you for flagging the issue.

Actually it looks like there's probably more to it than just changing the column-fill. With either of the options I suggested, if the items don't distribute evenly across the number of columns, it makes the middle columns the longest, which looks a little weird (and is different from the Grid display option which weights the longer columns to the left). Examples below using the Gin theme.

Column display: 3 columns, column-fill: balance

Grid display: 3 columns

(Original for context) Column display: 3 columns, column-fill: auto

Just an update on this issue.

• The columns CSS is triggering a bug in Chrome browser and its ability to handle the column-fill rule value of auto or in ability I should say.
• Also, the base CSS style names being added to grouped options (ex radios and checkboxes) by the base theme stable have changed. .form-checkboxes and .form-radios are no longer added to the div element wrapping the field's grouping of items.

in case you need a quick fix for the Chrome bug try the following:

-moz-column-fill: auto;
column-fill: initial;
