I'm working with one company in the UK for a long time, they provide SEO services. Sometimes they require some plugins. This WordPress plugin was done in the bounds of one such cooperative project.
This is an ordinary WordPress plugin, using standard solutions. The main goal of the plugin is the creation of product lists by using uploading of CSV files. Each upload can be deeply configured.
The user sets the number and order of columns. Each column maps with CSV file columns. The table of products loads from a CSV file and this table may be customized by using different CSS classes or definitions of style properties for the table and each column in the table.
Each such product list can be created as a WordPress shortcode or as a new page in WordPress.
Please, take a look at the gallery below - all the main functionality of the plugin is shown there.
