Extending

To control the available tabs and characters, developers can filter the data set using the insertspecialcharacters-characters JavaScript (wp.hooks) filter.

For example, to create a character inserter that only provides currency symbols:

wp.hooks.addFilter(
    'insertspecialcharacters-characters',  // The filter name.
    'mycallback', // Our callback namespace.
    function( component ) { // The callback function.

        // Return the categories/characters to display.
        // The data structure is: { category: [ character data ], category2: ... }
        return {
            "Currency": [
                { "entity": "$", "hex": "", "name": "Dollar Sign", "char": "$" },
                { "entity": "€", "hex": "&#20AC;", "name": "Euro Sign", "char": "€" },
                { "entity": "¢", "hex": "&#00A2;", "name": "Cent Sign", "char": "¢" },
                { "entity": "£", "hex": "&#00A3;", "name": "Pound Sign", "char": "£" },
                { "entity": "¥", "hex": "&#00A5;", "name": "Yen Sign", "char": "¥" },
            ]
        };
    }
);
