Hi there!

Thanks for contacting us.

There is no default option to use the "Read More" in Text Block as per my knowledge. Sorry about that.

Here is all about Text Block addon: https://www.joomshaper.com/documentation/sp-page-builder/text-block

Note: Customization support is prohibited here.

Have a nice day!

Hi

Thanks for contacting us. Sorry there is no default way to do that. You have to customize it yourself as we do not provide customization support. Hope you understand.

-Regards.
