If you create a view in which you use a shortened text (or summary), then you want the visitor with the Read More ... link, can read the full text.
Problem: the Read More ... link appears always. Even where the shortened text is also the full text. This is disturbing as on click, the same text appears identical. Completely redundant.
We can solve this problem. The following print shows Read More ... but it does not appear in the second row. All text has been shown
First you create the view with the following fields.
Body: is shortened
Body: full size, but hidden. This field will serve to determine how big the body field is.
Link: the Learn More link, hidden because we are going to show it or not in a conditional field
Conditional field: you need to install the module for that. Here we examine if the field full size is greater than our abbreviated version. If so, we then show Read More .. if not, we show nothing.
Make sure you choose the right body field (the full value )
You get now the following view.
