The native WP Bakery Page Builder plugin provides an element “Progressbar”, which can also be used to display skill sets. However, that element is limited in functionality. For example, all bars within the same set share one color and the color choices are limited. That’s why “Composium – AP Bakery Page Builder Extensions” includes a new element “CP Skillset”. In conjunction with a custom post type to provide the data for each skillset, you are now able to assign custom colors to each skill, among other improvements.
