Container block with settings that can have other blocks nested. Developers may also use it to create their own blocks making use of the build-in settings and controls.

== Description ==

This block is a container that can have other blocks nested. It comes with several settings:

* Background image, fixed, color & opacity
* Content align, max-width, text color
* Border width, color & opacity
* Shadow width, color & opacity
* Padding top, bottom, left, right, responsive paddings

Developers: The plugin comes with a filter to register your own block based on this one. Check the *How can I use the filter to create my own block?* section for more info.

== Screenshots ==

1. Block edit panel.

== Usage ==

This block will be added inside the blocks inserter menu under the *Melonpan Blocks* category.
Once added in the page you can edit its settings and add other blocks inside.
You may even add this same block type inside.

== Installation ==

Installation from the WordPress admin.

1. Log in to the WordPress admin and navigate to *Plugins > Add New*.
2. Type *Melonpan Block - Container* in the Search field.
3. In the results list *Melonpan Block - Container* plugin should appear, click **Install Now** button.

== Frequently Asked Questions ==

= How can I use the filter to create my own block? =

The plugin comes with a filter to register your own block extending this one, to make use of the settings that come with it.

**Notes**
You can choose from the available settings, listed below, and assign the block's InnerBlocks properties to customize it.
You may also pass your own attributes, inside the **custom** attribute, this adds a class to the **.mbc-container** div. Check the *How can I add a custom attribute?* section for more info.
Also note that the align attribute is handled by Gutenberg so although you can deprecate the control, the class that the old block had assigned will remain.

**Steps**
First, you need to [enqueue your script in the editor](https://wordpress.org/gutenberg/handbook/designers-developers/developers/tutorials/javascript/loading-javascript/).

Inside your script call the filter in the following way (make sure *Melonpan Block - Container* plugin is active):

    // Custom block registration example using the filter.
    wp.hooks.addFilter("melonpanBlockContainer.createBlock", "my-plugin/my-block", blocks => {
        return blocks.concat({
            // These are the default block registration properties. For more available properties:
            // https://wordpress.org/gutenberg/handbook/designers-developers/developers/block-api/block-registration/
            blocktype_props: {
                name: "my-plugin/my-block",
                title: "My Block",
                icon: "carrot",
                category: "common"
            },
            // These properties will be passed to the InnerBlocks component. For more info:
            // https://github.com/WordPress/gutenberg/blob/master/packages/editor/src/components/inner-blocks/README.md
            innerblocks_props: {
                template: [["core/quote"], ["core/image"]],
                templateLock: false,
                allowedBlocks: ["core/quote", "core/image"]
            },
            // Use this property to add extra props to the container, content or background divs.
            extra_props: {
                container: {
                    id: "my_id",
                    className: "my_container_class another_class"
                },
                content: {},
                background: { className: "my_bg_class", style: { opacity: 0.5 } }
            },
            // This is the list of all the available properties and their default values.
            // Settings are opt-in so only the ones that are passed will be used.
            // If an empty object is passed (for example, background_color:{}) the default values will apply.
            // Set the "show_control" property to false if you want to apply the setting
            // with the default value but hide the control from the editor.
            settings: {
                // Check the "How can I add a custom attribute?" section for more info.
                custom: {
                    example_attribute_name: { default: "value_A" },

= How can I add a custom attribute? =

When creating your own block using the **melonpanBlockContainer.createBlock** filter, you can add custom attributes.
This setting is meant to be a helper that adds a class with the name and value of the attribute.
One of the advantages of using it rather than the *blocks.registerBlockType* filter is that it should work if you need to deprecate the attribute.
Keep in mind that it will simply add a class in the **.mbc-container** div, and that a *string*, *number* or *boolean* value can be used.
If the attribute is a *string* or *number* the class will include the name and the value (example_attribute_name => **.mbc-example_attribute_name-the_value**).
If the attribute is a *boolean* the class will include the name and *enabled* or *disabled* (example_attribute_name => **.mbc-example_attribute_name-enabled**).
To add a control for the attribute you may use Gutenberg filters. Remember to remove the control if you deprecate the attribute.
Here is an example of adding a control using Gutenberg filters:

    const { __ } = wp.i18n;
    const { addFilter } = wp.hooks;
    const { createHigherOrderComponent } = wp.compose;
    const { Fragment } = wp.element;
    const { InspectorControls } = wp.editor;
    const { PanelBody, RadioControl } = wp.components;

    const withMyAttributeControl = createHigherOrderComponent(BlockEdit => {
        return props => {
            if (props.name !== "my-plugin/my-block") {
                return <BlockEdit {...props} />;
            }

            const { setAttributes, attributes } = props;

            return (
                <Fragment>
                    <InspectorControls>
                        <PanelBody title={__("My Panel")}>
                            <RadioControl
                                label={__("My attribute")}
                                selected={attributes.custom.example_attribute_name}
                                options={[
                                    {

                                    {

                                    setAttributes({
                                        custom: {
