Customizing Components#

You are able to customize the existing Volto components using an easy pattern in the customizations folder. You have to identify and locate the component that you want to customize, let's say the Logo component in Volto source code.


Those familiar with Plone's JBOT customizing add-on will recognize this pattern since it works the same way, except that here you have to create exactly the same folder structure of the original instead of using the dotted notation used in JBOT overrides.

You can override virtually any component that lives inside the src folder and adapt it to your needs, without touching the original (source) one. Components are named in a semantic and approachable way.

In order to identify them, you can use several approaches the main one using React Developer Tools then you can inspect the app and find out the name of the component (the name of the tag), then search for it in the Volto source code.

To override the component, use the same folder structure that the original component has in the Volto source code and place it inside the customizations folder.

Customizing the Logo resource#

So, for example, if we want to replace the Logo which is located in Volto at components/theme/Logo/Logo.svg, the folder structure needs to match the folder structure of Volto in the customizations folder. So the final path of the new overridden component will be: customizations/components/theme/Logo/Logo.svg.

Change The Tags Component#

When overriding components, we follow the same approach. We will copy over the original component from the Volto source code, then amend the imports (if any are required) to match the current folder structure. Point Volto source code using @plone/volto module instead of relative paths and other amendments required.

Locate the Tags.jsx file and override this file so that there is a label in front of the tags with: Tags:.

    * Tags component.
    * @module components/theme/Tags/Tags

    import React from 'react';
    import { Link } from 'react-router-dom';
    import PropTypes from 'prop-types';
    import { Container } from 'semantic-ui-react';

        * Tags component class.
        * @function Tags
        * @param {array} tags Array of tags.
        * @returns {string} Markup of the component.
    const Tags = ({ tags }) =>
        tags && tags.length > 0 ? (
            { => (
            <Link className="ui label" to={`/search?Subject=${tag}`} key={tag}>
        ) : (
        <span />

        * Property types.
        * @property {Object} propTypes Property types.
        * @static
    Tags.propTypes = {
        tags: PropTypes.arrayOf(PropTypes.string),

        * Default properties.
        * @property {Object} defaultProps Default properties.
        * @static
    Tags.defaultProps = {
        tags: null,

    export default Tags;

The final path of the overrided component will be customizations/components/theme/Tags/Tags.jsx.
