Question: I noticed in my wordpress/woocommerce setup that every time i add a tag to a product or a blog post. It adds that tag as a class into the listed item (Product/blog)

I also noticed it adds a class in the same place for every category i put these post items into.

How can i prevent wordpress and woocommerce from addings these tag and category names into my html markup as classes? As i do not need them and its creating a mess. 

Thanks for any help! I could not locate a similar function anywhere.

Answer: 
You can (at the moment) not use InnerBlocks more than once within a block. However, you can bypass this by using a template for your InnerBlocks that contain Blocks which support InnerBlocks instead, like the core/column block.

Like this:

```
wp.element.createElement(InnerBlocks, {
      template: [['core/column',{},[['core/paragraph',{'placeholder':'Inhalt linke Spalte'}]]],['core/column',{},[['core/paragraph',{'placeholder':'Inhalt rechte Spalte'}]]]],
      templateLock: "all",
      allowedBlocks: ['core/column']});

```

Some time ago, i wrote a Block for a content/sidebar block with align left/right attributes, worked exactly like that.

Happy Coding!
Only one Innerblocks per block instance is allowed, as described in [Gutenberg official Innerblocks source documentation](https://github.com/WordPress/gutenberg/tree/master/packages/block-editor/src/components/inner-blocks). A workaround for distinct arrangement is also provided.
