When applying a custom menu to the Abundance Sub Menu with the Stretched layout mode enable. The Sub menu is shifted below the Main navigation on the left side (and becomes invisible - white text on white background). The Sub menu is displayed correctly in the Boxed layout mode.
Work flow to reproduce the issue :
1) Fresh install of Wordpress 3.3.1
2) Activation of the Abundance theme 1.2.1
3) Activation of the WooCommerce 1.4.2 plugin
4) Load the default WooCommerce pages
5) Create a custom menu
6) Add the custom menu to the Abundance Sub Menu
7) Switch to the Stretch Layout
Thank you in advance for your help on resolving this issue.
