Once you have set up your blog index and blog posts, you can link the layers in the index to the post.
Simply click on the layer, go to the links tab and link it to the 'First index post', or whichever number it is, depending on how many posts you have in the index section. You only need to do this to the one section and it will automatically link to the correct posts once it's published.
Please note that in order to add the link to any of the text, you will it to be a button, instead of a paragraph text box. From here, you can stylise the buttons to look the same as a text box (removing corner radius and background).
