How can I fix the sub-menu button issue on my mobile site?

[tarekanani]

 I have a problem with my mobile menu function when I press the + button it doesn't open the sub-menu I did search about it in the Shopify customizer and I didn't find anyway to customize it I don't know where to play with it in the code .

Hi @tarekanani ,

Go to Themes => Edit code

- In the plugin.css file, add the following code at the end of the file:

.offcanvas-mobile-menu .offcanvas-wrapper .offcanvas-inner-content .offcanvas-navigation .menu-item-has-children .menu-expand {
  z-index: 1;
}

Hope it helps @tarekanani

Hello @BSS-Commerce 

Yes, I added the code and the button works but it is not showing the sub menu items. but I noticed that this happened since I changed the + button color by a custom CSS code is this a relation with what happens?  and how can I do both without affecting the expanding function?  

thank you so so much for your reply I appreciate it so much
