The shrink column feature isn't enough

Have to agree with other comments, the shrink column feature isn't enough. You need to be able to have multiple columns often.

The lack of support for this feature has me going to another provider, sorry.

You can split your form up to 6 columns. Of course, the fields must be small enough for this.

You can edit the width of the fields with CSS codes. Please see this article.
