To customize the styling of the 'How Many People' dropdown in a Contact Form 7 (CF7) form, you'll need to use specific CSS for select elements. The initial attempt with '.wpcf7 input[type=select]' is incorrect since you should be using 'select' with the proper selector. Focus on '.wpcf7 select' to effectively change the styling of your dropdowns, such as background color and borders, similar to how you've styled the input fields.
To style select dropdowns in Contact Form 7, use the proper CSS selector targeting the select element, such as '.wpcf7 select'.
