Multi-dim dropdowns are misaligned when they wrap to more than one row

[rakyi]

Description

Alignment and spacing of the multi-dim dropdowns is ugly when they wrap.

Expected behaviour

They should align vertically and the spacing between the rows should be the same as the spacing between the dropdowns in a single row.

Steps to reproduce

Steps to reproduce the behavior:

1. Create an mdim that has enough dropdowns to make them wrap to the next row
