Display Conditions
Every Page and every Element in HELIO shares a truly subtle, but very powerful, superpower: the Display Condition. It lets you control whether something is visible to your operators or if it stays out of the way.
Display conditions can be combined with many Dynamic Properties in order to make your HMI react intelligently to its context, without adding complexity. This opens up a lot of possibilities: Show advanced settings only to logged-in administrators. Hide elements when screen space is limited. Reveal information exactly when and where it's needed and nowhere else.
In short: display conditions help you build HMIs that are not just functional, but aware, focused, and user-friendly.
