Bulma 1.0 : Drop down menu in a fixed grid is hidden by any other fixed grid

[jbrazeau]

This is about Bulma 1.0 fixed grid and drop down menus.

Overview of the problem

This is about the Bulma CSS framework I'm using Bulma version 1.0.0

My browser is: chrome / firefox

I am sure this issue is not a duplicate? Spent a few minutes to lookup in the issue repository, but I didn't find any related issue.

Description

The drop menu content of a drop menu button that resides in a fixed grid is hidden by any other fixed grid that is below.

Steps to Reproduce

I've created a trivial sample with :

• a fixed grid with 2 rows / 4 cells : the top left cell contains an expanded drop down button, the menu overlaps the second row (which is good)
• a second fixed grid with 1 row / 2 cells : the menu is hidden by the grid (which is a problem)
• a column is inserted after : the menu overlaps the columns (which is good)

The basic HTML that isolates the problem is available in code-pen (so that it is trivial to reproduce) : https://codepen.io/Jean-Fran-ois-Brazeau/pen/bGJKeVm

Expected behavior

The drop down menu is expected to be fully visible, even over another fixed grid.
