Show/hide blocks based on context value


#1

This would provide the ability to dynamically show or hide any dashboard block based on the value of a context variable (or query parameter/attribute value).

Some questions here …

  • Why, specifically, do you want to hide certain dashboard blocks based on dashboard context values? Is there sensitive information within blocks that you do not want to share with certain users?
  • How would the dashboard layout change if a block in the middle is hidden? Is there just a hole where the block used to be? Does everything collapse into place as best as it can figure without human intervention? Is it up to the dashboard editor to manage these layouts manually?

Maybe if you can provide a little more information about your use case, we can come up with a solution or write up your request as a broader feature.

Great question!

The use case for us is based on the fact that we have many customers that have differences that can be accomodated by different configurations of the contorl system. Let’s say that our device can accomodate up to 30 different types of sensor readings, but some applications may only be using 12 because some of the sensors don’t make sense for thier particular use case. For example, lets say its an engine. Some engines might be connected to generator which involves some sensor data realted to AC voltage, current, frequency. That AC data makes no sense to someone using an engine in a pumping application but the basic sensor data does make sense. For this person, we would disable the AC gauges and simply not show them.

What I envision is a more dynamic dashboard that prevents creating too many duplicates of dashboards with variations. Right now, we could make new dashboards for each customer but that creates an administrative burden.

The layout is somewhat of a delimma. There are two approaches I can think of. The first would involve creating sections and grouping things together so you can hide a group of gauges without it looking like something is missing. The second would be some kind of auto layout based on a criteria similar to what content management systems like Drupal would use. You could assign a “weight” to each gauge and change what order the gauge displays if its present.

In essence, any method that can prevent creating many duplicates with small variations, that would solve the problem. Perhaps some kind of object oriented approach might be helpful, where a base dashboard is specified and variations of the base could be specified quickly and easily and tied user or group tags? Just thinking out loud here.

Thanks
