A new how-to article has been released that covers the process for highlighting a text box in red when a button is clicked and the field is empty in a K2 View. The article outlines the full configuration, starting with the initial setup of the view and continuing through the creation of an IsBlank expression, transferring the expression result through a rule, and applying conditional formatting based on the evaluated outcome.
This approach enables validation to occur only after a user action, preventing unwanted highlighting on initial load and providing a cleaner and more purposeful interaction flow.
