i would like to create a simple grid. You should get two columns (later more) to put content in there. But not only simple text. All content types should be available

My edit function

registerBlockType(
    'grids-2col', {
        title: '2 Spalten',
        icon: icon,
        category: category,
        attributes: {
            paragraphLeft: {
                type: "string",
                selector: "div"
            },
            paragraphRight: {
                type: "string",
                selector: "div"
            },
        },

        edit: function (props) {
            var attributes = props.attributes,
                className = props.className,
                setAttributes = props.setAttributes;
            var paragraphLeft = attributes.paragraphLeft,
                paragraphRight = attributes.paragraphRight;
            return [

                        })
                    )
                )
            ];
        },

The Problem is that the what i write in the left box ist cloned into the right one. How ist it possible to make more than one InnerBlock.

It works fine with RichText instead of InnerBlocks.

• If your block is just a set of columns with predefined inner blocks, would this not be better as a block pattern? It seems a waste to create an entire block that's the same as existing blocks. Just pre-assemble the pattern and register it – Tom J Nowell ♦ Commented Jan 16, 2021 at 23:08

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!

You can only have 1 innerblocks, it doesn't make sense to have separate sets of children. Just like a <div></div> element only has one "inside".

The official solution is to use composition.

So do what the core/columns block does, and create a new block that can only be placed inside.

E.g. core/columns block can only contain core/column blocks. And core/column blocks can only be put inside a core/columns block.

Likewise, if you want a container with rows, you need a container block and a row block.

When building your containing block, pass the allowedBlocks prop to th InnerBlocks component.

When registering your internal block ( column/row/etc ), specify the parent option and say that it can only be inserted inside your container block.

This also means your sub-block has attributes, and can be selected. This means you can add options like width/height/style.

If you need to restrict the number of child areas, you can use a template to pre-fill the sub-blocks and lock it so that they cannot be added or removed

Only one Innerblocks per block instance is allowed, as described in Gutenberg official Innerblocks source documentation. A workaround for distinct arrangement is also provided.
