I'm trying to make a a webpage that has a conditional dropdown box using html and javascript. Say it's a certain day in the week like Monday I need a different dropdown box with different options when it's Thursday; however some days may have the same options. Originally I had two drop down box one when the person clicked what day it was and then the dropdown box would appear, but I was wondering if there was a way to do this automatically using a javascript function and also creating a function that only displays a certain dropdown list.
