I'm having a little issue with hiding an option tag in my project. When I click the box, the select theme option is still there, but when I click it again, it does what it should do and hides. Any idea on why this is happening?
Variable to grab the select theme option
const firstOption = $("#design").children()[0];
function to hide select theme option on click
$("#design").click(() => {
$(firstOption).hide();
});

I don't know how this relates to jQuery, but I know folks working directly with CSS often get confused about the initial state of an elment's "display" setting being empty instead of "block". So they write toggle code that thinks the element is hidden when it doesn't see "block" in the display .. and then promptly sets it that way .. which of course makes no visible changes.
