We'll create fresh WordPress site with Dynamic Product Titles for Variant Options installed. You have 20 minutes to test the plugin after that site we'll be deleted.
This is a simple plugin that when ‘active’, will allow users on your site to dynamically change a variant product title on the product page to show the selected variant option name at the end of the default title.
‘ProductA’ which has the attribute ‘Colour’ with ‘Blue’ and ‘Red’ as options, would see a default title of: ‘ProductA’, but when the first variant option is selected, the title would change to ‘ProductA – Blue’, and when the second variant option is selected, the title would change to ‘ProductA – Red’.
Note: If the default value is selected again after a variant has already been selected, the default title will again be used.
