Hi Greensock Community,


First and foremost, It's been three days since I started learning GSAP (I'm a super newbie) about this web animation technology.  I have this HTML select which I want to animate the HTML option(s) tag when the user clicks the HTML select tag. I make a basic animation to test out, but the element (options) tag is not animating but when I checked the developer tool it seems TimelineMax is working I'm not sure if the option tag elements itself is can't be animated.  Please need suggestion on this.

I've never messed with <option> elements, but it doesn't look like you can change the position or transform it. If you animate something else like the backgroundColor, you'll see it work.

You can't animate option tags, plus styling them consistently is almost impossible. You can instead use something like jQuery UI which replaces your select tag with custom HTML that you can style or animate as you like. There are many other libraries/frameworks that do same thing but be sure to check if they are accessible.

Hello @keepRunning and welcome to the GreenSock Forum!


Yeah browsers wont even let you style specific CSS for <option> HTML elements. Chrome or other webkit based browsers used to allow CSS to style both <select> and <option> elements, but they have been pretty poopy pants about styling <option> tags lately. So the browser will reject certain CSS properties for visual, layout, and transforms on <option> tags. The HTML DOM interface won't allow it. :) The browsers only allow things like font-size, font-family, font-variant, font-style, color, background-color, background, etc like Blake said above


When i look at the spec for <option> tags there is no mention of this





Only other route is like Sahil advised is where the original <select> tag is hidden. And then you create a custom dropdown with animated option tag using <ul> and <li> tags.. or use a jQuery UI dropdown select that is jQuery custom HTML.


Happy Tweening! :)

Always good info from the Oracle of CSS. 


This is one of those things that should be so simple, but is made into Mission Impossible. It reminds me of vertically centering something back in the day. It took a team of 16 people working 12 hours shifts for 6-8 weeks to vertically center some content in a div. :D
