I should first mention I am fairly new to wordpress and web development.
I was given the task to update an existing site which includes the navigation bar. I have been digging through code trying to figure out where the actual code has been stored for the nav. The site is a custom build theme which looks to be built using the "Bones" theme. I've tried using the customizer to alter nav but there are no options available for what is needed. I've accessed the hosting through ftp and reviewed the php files in httpdocs/wp-content/themes etc. The closest thing I've found was in the header.php in the themes>"custom theme">header.php, however, this does not contain the full menu it only references the logo and one outdated dropdown button. I am getting nowhere.
I hope this makes more sense with a visual.
The site is cowboycauldron.com
I appreciate any help.
