Hi! Because the forum is working great today I thought of asking this question to :) So, I have a registration entity where I register who is joining what course. This is how the (registerd account) vieuws it (so here it should only be the unregister button) How can I make the button register visible ONLY when in the entity Registration the row exists with the course and current account? Gracias!
You could use the ‘ShowByCondition’ widget. The widget allows you to hide a parent container by returning true or false from a nano- or microflow.
If you don’t want to rely on a widget you could use a dataview with a Nanoflow datasource where you retrieve the registration that is associated to the current user and the course. Inside the dataview you can use the expression ‘$currentObject = empty’ to show content when the registration does not exist.
