If you want your dropdown menu to be dark with white text, then select Dark Theme from the Bootstrap menu.
If you want your dropdown menu to be white with dark text select the light Theme from the bootstrap menu.
These are the most common settings for most websites. It’s best visually and easier on the eye.
If you do however want extra colours which aren’t very common. Then just add the code provided by Norm into the ‘Additional CSS’ section of the code editor.
For the example below, set the bootstrap theme to ‘default’.
nav .dropdown-menu .nav-link:not(.blocsapp-special-menu .nav-link)
{
color: red!important;
background-color: green!important;
}
This will change the text to Red and the Menu Colour to Green. You can obviously change these to what you prefer by changing the colours or if you just want text to be changed and not the menu colour, then remove the background-color line.
