Dropdown animation only works once smooth on first open, then snaps open/closed after

Hey everyone,

I’m having an issue with a dropdown animation that I built in Webflow.

  • It’s a native Webflow Dropdown (not a custom div).

  • The dropdown list has a class like Dropdown List 5.

  • I’m using Dropdown open/close interactions to animate its height and opacity.

  • On the first open, it animates smoothly.

  • On the second open, it just snaps open and closed — no smooth animation.

  • I’ve already tried:

    • Rebuilding the animation from scratch

    • Resetting inline styles

    • Using class-based targeting (Only children with this class)

    • Even making a brand new dropdown in the same section

The strange thing is that one instance works perfectly, but copies of it or new ones made with the same animation don’t.

Is this a known issue with Webflow dropdowns or class-based IX targeting?
Could the built-in dropdown display:none behavior be overriding the animation after the first cycle?
What’s the best fix — keep using the native dropdown or rebuild as a custom dropdown using divs and IX only?

I would like if I don’t need to code out the animation for the drop down but I will admit I have yet to try that

Thanks in advance — any insight from someone who’s hit this before would be great.
