How do I open a sub-system when clicking on an element?
This guide describes how to add a second "layer" of elements + connections to your map that only appear when double-clicking a certain element. You're essentially linking an element to another map in the same project through a URL field. This allows you to add additional data to your map, that might not always need to be visible in the main map.

Double-click an element to access a sub-system
Here are the steps to do so:
- 1.Create your main map, as you want it to be visible to your viewer upon opening the Kumu project (this is your first "layer")
- 2.Copy the URL of this main map from the browser bar
- 3.Click on the first dropdown in the top-left corner of your project, and choose "+ New Map"
- 4.Create the second map that shows what you want it to look like when someone double-clicks an element (this is your second "layer")
- 5.Click to add a map description to your second map and write "Return to main map". Hyperlink these words with the URL you copied at step 2
- 6.Then copy the URL of this second map directly from the browser bar
- 7.Go back to your main map (top-left corner dropdown) and add a field called "URL" to the element you want to be able to double-click
- 8.Paste the URL from step 6 as the value in that field
- 9.Now if you double-click that element on your map, it'll navigate you to the other map
