Hey guys So I want to solve the following issue: Our agents categorize all tickets. For some tickets we would need further insights which is why we add text fields, after the agent has selected a certain category, where the agents then can insert information. But there is no introduction or explanation of what the agents are supposed to type in. I want to change that, e.g. "why does the customer want a refund" We have several of those text fields for certain main ticket categories. My questions are: 1. How do I insert the explanations? 2. How can I change the explanation depending on the main category the agent selects previously? Do I have to add all the text fields and adapt them individually? Thanks in advance, Julia
