MultiStores Magento 2 Theme - Fix MageMenu & Make Small Changes
Timeline is 3 days max.
MultiStores is a Magento 2 theme that has been fixed by a few developers already. There is an extension of this theme called MegaMenu that is showing a error I am not aware of how to fix. Also, when a user opens MegaMenu with the Administrative Dashbaord is shows a very basic white page with some UI controls, so it appears to be broken.
Also, please fix any error on the frontend and backend while compiling the code in Developer Mode. Currently there is one error that shows in the attached text file.
Lastly, I have some CSS and PHTML fixes I need help with.
1) (Fixed)
2) Changed the CSS color of hover menu item within horizontal MegaMenu (parent and child)
3) Add dropdown to static links in right header links
4) Make sure that a custom CSS file currently in static files is able to be picked up after each static deploy
5) Attached vertical MegaMenu is not consistently rendering the JS that collapses the left menu into All Products. Please find the issue and make sure it loads all the time or else the whitespace underneath will appear.
6) Hide pricing for anonymous users. Users must be logged in to see pricing.
