Problem with MixItUp plugin


I use plugin MixItUp (

I did everything as in the instructions to the plugin. But when I click on the button, all items disappear



Invalid/mismatch of classes <=> data-filter values


But I didn’t write the underscore _

In the constructor, these underscores do not exist! They were framed by WebFlow itself! WebFlow distorts class names.


I added underscores in data-filter values for buttons, but items still disappear.


No. Webflow was making them valid class names. Classes can never start with a numeric character.

I’ll give you another hint, class selectors need to start with a specific character.


Thank you. I fixed it. Now everything works as it should. :relieved:
