Masonry supports up to three tiers of main menu navigation using two different styles on desktop - 'Flyout' ( on our Flamingo demo store ) and 'Inside' ( on our Coyote demo store ).
More details on setting up Shopify navigation are here.
Tip: If some of your menu options are already expanded when you visit your homepage, this is just a simple set up issue - not a bug. You won't need to alter any code to fix it. The likely problem here is that you have set the top menu items to link to your homepage. So when you visit the homepage, it intentionally expands these active items. You need to set each of these top-level menu items to link to web address # - the hash/pound symbol.
Add an announcement bar at the top of your Masonry Shopify theme site, to promote your latest offers - add a link to a specific product or offer page, and choose a colour for the bar.
You can add promotional links in the style of buttons to the bottom of your navigation, ideal for adding calls to action like 'SALE NOW ON' and 'OUR STORY'.
Payment icons are pulled directly from Shopify based on your payment settings.
Footer text such as "Powered by Shopify" and "Theme by Clean Themes" can be edited in the Language Editor.
