If we want to translate a post (for example) we will go to the post area of the source language that we are going to use for the translation. In this example we are going to create a post (in Spanish) and we are going to translate it into 3 languages at the same time: Catalan, English and French.
The first thing is to go to the section of the post and fill out a new one.
We activate all the languages we want to translate and create their corresponding categories. The title, slug, excerpt and description will be translated.
Once created (published or draft), you can access them directly from the link of each language.
There we will be able to see the translated elements.
